can anyone suggest somesort of plugin that shows the colors from image/colors.RGBA{} ?

hello everyone :) noob here, trying to work on a gui and have to use the image/colors package and i know how there's like a button to adjust the colors when working on a css file that appears near the line number, is there something similar with the image/colors.RGBA{} some kind of plugin perhaps?
