@alltheyuriz I think you misunderstand how colors work in RMs.
the windowskin picture has a grid of colors that is assigned to numbers.
color 0 is basically the first index in that grid - and it is only white in the default windowskin or in other windowskins that use the same grid in their pictures.
and any place where a text code is given, you can change the number to get it to do something else.
that includes the tag field in the plugin properties mentioned above.
If you don't want to use color number 6 in nametags, then change the property to use another color index - or remove it or add other tags there and so on.
that is the sole purpose of that property - so that you can set the color and font properties for the nametag there without needing to repeat them in every message
