I am wondering if it is against the TOS to just change the color of your adsense units manually. Sometimes it is easier just to copy and paste your AS code when all you have to change is the background color. Would I get in trouble for that? Maybe I am a little lazy
There's nothing wrong with JUST changing the colorcode. If you change anything else.. then it would be.
easy method if u feel it will be a problem, download any color picker software (there are many free) and find the hexa decimal code of the color, u can enter this code in adsense site, so u get exact colour u want.
