I noticed when trying to make a colourscheme that the colours don't match exactly to what you set them as. For example if I set the background colour as "#2B2B2B", then apply the theme, screenshot and colour-pick in GIMP, then the real colour is #303030.

(Also interesting note, the same issue occurs in the program Glow, which is also written in Go. Not sure if this is relevant)
