I just finished my C# console application code for a project and would like to add some color to my font. I would love to be able to use a custom color - orange. Is there any way to do this?
This is the code I have been using to change colors in the past, but it doesn't offer orange:
Console.ForegroundColor = ConsoleColor.Magenta(and so on);
Is there a way to maybe insert a hex value for the color or something similar?
The list found at http://msdn.microsoft.com/en-us/library/system.console.backgroundcolor.aspx
I believe are the only supported colors in console. No hex allowed.
Black
DarkBlue
DarkGreen
DarkCyan
DarkRed
DarkMagenta
DarkYellow
Gray
DarkGray
Blue
Green
Cyan
Red
Magenta
Yellow
White
EDIT
Get the working project files off my public Repo
https://bitbucket.org/benskolnick/color-console/
But on further investigation you can do a lot of work to combine red and yellow to get orange. Follow the example here. Not going to re-post wall of code.

That Doesn't give you access to more colors but does lead in the correct direction. You will need to do some PINVOKE work but I was easily able to get orange, or any other RGB color into console.

And then if you want to use Orange or any other color you can do a simple call to SetScreenColor
static void Main(string[] args)
{
Color screenTextColor = Color.Orange;
Color screenBackgroundColor = Color.Black;
int irc = SetScreenColorsApp.SetScreenColors(screenTextColor, screenBackgroundColor);
Debug.Assert(irc == 0, "SetScreenColors failed, Win32Error code = " + irc + " = 0x" + irc.ToString("x"));
Debug.WriteLine("LargestWindowHeight=" + Console.LargestWindowHeight + " LargestWindowWidth=" + Console.LargestWindowWidth);
Debug.WriteLine("BufferHeight=" + Console.BufferHeight + " WindowHeight=" + Console.WindowHeight + " BufferWidth=" + Console.BufferWidth + " WindowWidth=" + Console.WindowWidth);
//// these are relative to the buffer, not the screen:
//Debug.WriteLine("WindowTop=" + Console.WindowTop + " WindowLeft=" + Console.WindowLeft);
Debug.WriteLine("ForegroundColor=" + Console.ForegroundColor + " BackgroundColor=" + Console.BackgroundColor);
Console.WriteLine("Some text in a console window");
Console.BackgroundColor = ConsoleColor.Cyan;
Console.ForegroundColor = ConsoleColor.Yellow;
Debug.WriteLine("ForegroundColor=" + Console.ForegroundColor + " BackgroundColor=" + Console.BackgroundColor);
Console.Write("Press ENTER to exit...");
Console.ReadLine();
// Note: If you use SetScreenColors, the RGB values of gray and black are changed permanently for the console window.
// Using i.e. Console.ForegroundColor = ConsoleColor.Gray afterwards will switch the color to whatever you changed gray to
// It's best to use SetColor for the purpose of choosing the 16 colors you want the console to be able to display, then use
// Console.BackgroundColor and Console.ForegrondColor to choose among them.
}
Since Windows 10 Anniversary Update, console can use ANSI/VT100 color codes
Use sequences:
"\x1b[48;5;" + s + "m" - set background color by index in table (0-255)
"\x1b[38;5;" + s + "m" - set foreground color by index in table (0-255)
"\x1b[48;2;" + r + ";" + g + ";" + b + "m" - set background by r,g,b values
"\x1b[38;2;" + r + ";" + g + ";" + b + "m" - set foreground by r,g,b values
Important notice: Internally Windows have only 256 (or 88) colors in table and Windows will used nearest to (r,g,b) value from table.
Sample code:
using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Runtime.InteropServices;
using System.Text;
using System.Threading.Tasks;
namespace ConsoleApp1
{
class Program
{
[DllImport( "kernel32.dll", SetLastError = true )]
public static extern bool SetConsoleMode( IntPtr hConsoleHandle, int mode );
[DllImport( "kernel32.dll", SetLastError = true )]
public static extern bool GetConsoleMode( IntPtr handle, out int mode );
[DllImport( "kernel32.dll", SetLastError = true )]
public static extern IntPtr GetStdHandle( int handle );
static void Main( string[] args )
{
var handle = GetStdHandle( -11 );
int mode;
GetConsoleMode( handle, out mode );
SetConsoleMode( handle, mode | 0x4 );
for (int i=0;i<255;i++ )
{
Console.Write( "\x1b[48;5;" + i + "m*" );
}
Console.ReadLine();
}
}
}
Result:
Read about it in MSDN: Article 'Console Virtual Terminal Sequences'
"\x1b[48;2;" + r + ";" + g + ";" + b + "m" "\x1b[38;2;" + r + ";" + g + ";" + b + "m" absolutely does NOT limit you to 256 colors. I created a console based render engine and when I tested it on a bitmap of my car, the unique color count of a bitmap screen capture was 46,376 unique colors. –

\x1b[48;2; instead of x1b[48;5 you can use RGB(255,255,255) and create a rainbow like https://mcmap.net/q/219845/-ansi-colors-and-writing-directly-to-console-output-c –
Monodrama Expanding on the answer of Alexei Shcherbakov Windows 10 ENABLE_VIRTUAL_TERMINAL_PROCESSING here is a complete color code mapping so you have all colors and their respective numbers in one place:
Better late than never, but it appears this is now possible, on Vista and later at least. So I'll add this for future reference for others with the same question.
When I was looking to do this I came across Hans Passant's reply on MSDN:
I don't have access to Vista right now so can't try it. But something like this ought to work:
CONSOLE_SCREEN_BUFFER_INFOEX info; info.cbSize = sizeof(info); HANDLE hConsole = GetStdHandle(STD_OUTPUT_HANDLE); GetConsoleScreenBufferInfoEx(hConsole, &info); info.ColorTable[14] = RGB(255, 128, 0); // Replace yellow SetConsoleScreenBufferInfoEx(hConsole, &info); SetConsoleTextAttribute(hConsole, FOREGROUNDINTENSITY | FOREGROUND_RED | FOREGROUND_GREEN);
It will take a little bit of p-Invoking but should give you something to go on with.
It does not orange because that color is not one of the supported color for console. I mean, you can not get it even using windows API. If you want to verify it, take a look at the following piece of code:
public static class Win32
{
[DllImport("kernel32.dll", SetLastError = true)]
public static extern bool SetConsoleTextAttribute(IntPtr hConsoleOutput, short attributes);
[DllImport("kernel32.dll", SetLastError = true)]
public static extern IntPtr GetStdHandle(int nStdHandle);
}
public class Program
{
static void Main(string[] args)
{
foreach(var i in Enumerable.Range(0, 100)) // why "100"? it is just any number
{
Win32.SetConsoleTextAttribute(Win32.GetStdHandle(-11), (short)i);
Console.WriteLine("Hello");
}
}
}
Further proof this does not work (using the approach in Benjamin's link):
using System.Runtime.InteropServices;
namespace
{
class Program
{
[DllImport("kernel32.dll")]
public static extern bool SetConsoleTextAttribute(IntPtr hConsoleOutput, int wAttributes);
[DllImport("kernel32.dll")]
public static extern IntPtr GetStdHandle(uint nStdHandle);
static void Main(string[] args)
{
uint STD_OUTPUT_HANDLE = 0xfffffff5;
IntPtr hConsole = GetStdHandle(STD_OUTPUT_HANDLE);
SetConsoleTextAttribute(hConsole, (int)Colour.Red + (int)Colour.Green + (int)Colour.Intensity);
Console.WriteLine("Red + Green + Intensity == Yellow");
SetConsoleTextAttribute(hConsole, (int)Colour.Red + (int)Colour.Green + (int)Colour.Intensity + (int)Colour.Red);
Console.WriteLine("Yellow + Red != Orange");
SetConsoleTextAttribute(hConsole, 15);
Console.WriteLine();
Console.WriteLine("Press Enter to exit ...");
Console.Read();
}
public enum Colour
{
Blue = 0x00000001,
Green = 0x00000002,
Red = 0x00000004,
Intensity = 0x00000008
}
}
}
This method does not allow you to add anything that cannot be reached through ConsoleColor. It's a real shame as I too would love to add orange to my app. If anyone has found a way I would be very interested.
enum Colour is bit masks and should be ORed together, not ADDed together. That's why you can only get the original 16 VGA colors. 4+4=8 (or Red+Red=Intensity). –
Meier a bit late, i know. But one way to achieve colors that are normally not available in C# Console is to change the ColorCode of a color in the Registry. But be warned, this is propably the most unacceptable way to do it. Just open regedit (Win + R, then type "regedit"), go to HKEY_CURRENT_USER, open the key "Console" (At this point you should export the "Console" Key to restore it later). There you will see a list of values from ColorTable00 to ColoTable15. if you change, lets say, ColorTable10 from 0x0000ff00 to 0x0000a5ff (or 65280 to 42495) you will have an orange color when you use ConsoleColor.Green in the Console after restarting it. You can also change this value by code
using System;
using Microsoft.Win32;
namespace colorChanger
{
class Program
{
static void Main(string[] args)
{
Console.ForegroundColor = ConsoleColor.Green;
Console.WriteLine("Hello World");
RegistryKey regKey = Registry.CurrentUser.CreateSubKey("Console");
regKey.SetValue("ColorTable10", 42495, RegistryValueKind.DWord);
Console.ReadKey();
}
}
}
Of course that works with all other ColorTable-Values and Colorcodes but it is changed only for your User on your PC.
