You're absolutely right about the digits - I've tweaked them with some more 'high contrast' edges. I must admit that changing their colour would never have occurred to me - this level of post processing is already unprecedented for me!
Original idea Gyles, great contrast and interesting take on this theme.
I like the crisp clean lines of this, my only minor point is that the 90.20MHz is a little hard to read (shadow helps here) perhaps if that text was in red like the 'stereo' it would still be high contrast and easier to read.
