Which Windows version are you using? Note that on Windows 7 and 8 colors are not working in the default terminal. Use Alacritty

Doesn't seem related to #2122.

Colors don't seem to be working because they are using a completely different color scheme. The colors are gradiented in the picture, meaning they are using the new rgb color feature introduced in 20w17a (1.16).

An implementation must be made for this, in both MCC and the console handler.

(On the same vein as #2122, it might be nice to get a fallback color that is nearest to the specified RGB value if the terminal only supports basic color.)

The simplest solution would be to just use the dominant color, eg. convert the hex into rgb and then do manual checks for ranges, maybe there is an utility that could classify a color name based on hex.

This should do the job:

public static string getColorName(int[] myColor) {
	Dictionary<string, int[]> colors = new Dictionary<string, int[]>();
		
        colors.Add("red", new int[]{255,0,0});
        colors.Add("yellow", new int[]{255,255,0});
        colors.Add("green", new int[]{0,255,0});
        colors.Add("cyan", new int[]{0,255,255});
        colors.Add("blue", new int[]{0,0,255});
        colors.Add("magenta", new int[]{255,0,255});
        colors.Add("white", new int[]{255,255,255});
        colors.Add("grey", new int[]{127,127,127});
        colors.Add("black", new int[]{0,0,0});
		
	double temporaryDistance = double.MaxValue;
	string temporaryName = "";
		
	foreach(KeyValuePair<string, int[]> color in colors) {
		double rDistance = (double)myColor[0] - color.Value[0];
		double gDistance = (double)myColor[1] - color.Value[1];
		double bDistance = (double)myColor[2] - color.Value[2];
			
		double totalDistance = Math.Sqrt((rDistance * rDistance) +  (gDistance * gDistance) + (bDistance * bDistance));
			
		if(totalDistance < temporaryDistance) {
			temporaryName = color.Key;
			temporaryDistance = totalDistance;
		}
	}
		
	return temporaryName;
}

Eg. getColorName(new int[]{51, 153, 255})

Converting colors back to 16 colors on terminals that do not support other color codes seems a good idea 👍

@breadbyte Is it fixed?
