I've made 5 more sets of icons. The same (free) default icons but in blue, red and black, all for 24 Bits. I've changed the Violet one, as the borders weren't transparent, so it must substitute the existing. Also I think the names of the existing souldn't be "Retrofan...", because I only convert them.
I've also made a 256 colors version of the Black&Green one (I told some posts ago that the "Black&Red" is a typo that must be renamed Black&Green. BTW I've left there another Radio image, so just selecting this Buttons the radio changes.
This is the Red 24Bits one:
I've added also the Technics images remaped to 256 colors and I've made also the Black and Red buttons with 256 colors.
