I dont mind chipping into this post as I think its usefull
So going to give some smarters advice although this can change as often as you change your underpants
depending on version.
The first thing to notice in the color.xml is not many of the enteries are actually used by the app but there for reference kind of like a color chart you see when picking paint , you can ignore there and scroll down the list.
Anything looking like the above can be ignored and there are quite a few.
I think there are around 150 colors at the begining , then after the colors you come to
the ABC enteries again ignore them its only around line 260 that you come to what I would say are changeable colors
notice lines 261-263 these are noticable if you change them the list then goes back to useless color listings that you dont need to bother with (note reason they are included is if in an .xml file a color is set you can use these ).
the next group of colors you need to look at are the EPG section around line 356-364 these settings control the Program guide colors
I would suggest doing these as you THINK they should be saving and checking how they actually look ,then tweak untill you have it the way you want.
The next colors to look at are the hp_cyan enteries ,there are four of them around 394/397 these control your selection color on live tv etc. change them to pinkish tones and test you will recognise where they are.
Next down the list are the live enteries around 482-486 these are the colors used when you select EPG or tv guide and are taken to the screen where you select which group of programs you want to view like cinema ,sky sports ,bt sports etc. these are text colors and back colors selected and un selected , worth a little trial and error to get right
that should be enough to get on with for now
