Custom text color in C# console application?
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

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.
}
[Shameless self-promotion]
I'm working on a project that allows you to style console output in any System.Drawing.Color, including orange. Here's how you'd do it:
Console.WriteLine("writing to the console in orange", Color.Orange);
Project: http://colorfulconsole.com/
Since Windows 10 Anniversary Update, console can use ANSI/VT100 color codes
- You need set flag ENABLE_VIRTUAL_TERMINAL_PROCESSING(0x4) by SetConsoleMode
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();
}
}
}
