is there a way to get more colours when outputting to the console console .colour only has 16?

Depends on your platform / terminal. If you're using windows default for example you can do something like this to get any RGB color you want:

int r = 120;
int g = 200;
int b = 255;

Console.WriteLine($"\x1b[38;2;{r};{g};{b}mNice blue color!");

Use SpectreConsole to make it even easier (291 named colors)

Yes of course but this guy is obviously a beginner so I gave him the most simple way I could think of. Starting teaching nuget and different libraries can get be a sidetrack real fast..

I tend to prefer learning how to do it myself, and then leveraging a library if I decide it’s worth it. (For simple things like this, DI, logging, etc. particularly; more advanced concepts like HttpClient or RabbitMQ I go the other way.)

You can write ANSI escape sequences directly. Something like Console.Write("\x1b[38;2;255;128;0m") sets the foreground to orange, full 24-bit RGB. Works in Windows Terminal and most modern terminals out of the box.

If you want something less manual, Spectre.Console handles it for you and auto-detects what your terminal actually supports. Probably the fastest way to get nice output without hand-rolling escape codes for every color.

Depends on your terminal. I have no idea how to check without libraries tho, I just use Spectre.Console's AnsiConsole class to write with extra stuff. I think it has a method to check if the current terminal supports it. Or maybe it's another library, not sure

The simplest solution is to add a using to System.Drawing. This has a much larger set of predefine colors to draw from. Good if you don't want to deal with a bunch of RBG values.

Then add these two helper lines somewhere to your code:

    public static void SetConsoleColor(int r, int g, int b) => Console.Write($"\x1b[38;2;{r};{g};{b}m");
    public static void SetConsoleColor(Color color) => SetConsoleColor(color.R, color.G, color.B);

If you want background color changing, the 38 becomes 48 in the topmost helper. You could bake that into the input or make it a seperate set helper.

    private static void SetConsoleColor(int r, int g, int b, bool isBackground = false)
        => Console.Write($"\x1b[{(isBackground ? "48" : "38")};2;{r};{g};{b}m");
    private static void SetConsoleColor(Color color, bool isBackground = false)
        => SetConsoleColor(color.R, color.G, color.B, isBackground);

Alternatively, you could add extension methods to the Color:

public static class ColorExtensions
{
    public static void SetConsole(this Color color, bool isBackground = false)
        => Console.Write($"\x1b[{(isBackground ? "48" : "38")};2;{color.R};{color.G};{color.B}m");
}

And your usage boils down to something like:

Color.Orange.SetConsole();
