[FEAT] RGB Colorcode support

[leodlpy7]

Wanted features:

The keyColor-attribute should support RGB-Colorcodes for a more colorful output.

Motivation:

I am bored of the colors available and would like to customize them in a more flexible way using rgb. It would be great if you could implement the feature soon, I really miss it.

No.

38 means "Set Foreground Color"
The 2 after the 38 defines "RGB" mode.
the RGB values you want to set are directly after it.
So 38;2;255;128;0 means
Text is "Orange" with background unaffected.

You can add 1; before the 38 to enable "Bold" so 1;38;2;255;128;0 is Orange text that is more bold.
This wiki article explains what each number means
Note, some values are not supported.

Just a tip, some terminals do not support 24bit color and you might be limited to the 4bit color selection, you can also use the 8bit color selection by using 38;5;x
With x being the value of the color in the chart below that article from the link.
