Sorry, can't do blue ones
I've got the blue bananas:
Back in the days when the NTSC color TV system was being developed, a test color transmission of some fruit was done. Some practical joker took the bananas and painted them blue. In the NTSC color system, the color (more precisely chroma) is encoded onto a subcarrier, the phase indicating which color. Yellow 180o out of phase yields blue. The guy at the receiving test site would adjust the phase (commonly called "tint") to get the bananas right, but then the rest of the fruit would be wrong!
