I guess that with each personality comes different tastes (or the other way around). Regarding coding, each one of us has his/hers preferred colour scheme. If you don’t have yours is because you haven’t searched enough :-)
For Geany there are a bunch of pre made schemes which are quite nice.
I really don’t know about others… but, maybe because I am synesthetes I constantly feel the need to change colour scheme each time I change ideas about a project, or start a new development, or learning something new and big.
This time isn’t different, I found myself comfortable with the Vibrant theme on Geany =)
Actually so comfortable that I want to write it here, just in case for the future :-P
Find the colour scheme by Jason Wilson here =)
