Rainbow in a Tambourine

It's been a long time not seeing a rainbow. I can't even remember when was the last time I saw rainbow. As I long to see it I think of best way how to get a rainbow color. For the meantime, here's a rainbow in a tambourine.

For some who don't know what tambourine is; the tambourine or marine (commonly called tambo) is a musical instrument in the percussion family consisting of a frame, often of wood or plastic, with pairs of small metal jingles, called "zils". Classically the term tambourine denotes an instrument with a drumhead.
