Saturday Night at the Oldies: Songs of Color

Here is a sampling, starting with the determinable and proceeding to some determinates:

Donovan and Joan Baez, Colors
Ry Cooder, Yellow Roses.  A beautiful song. Give it a chance.
Bobby Darin, 18 Yellow Roses.  Never could understand why this tune is almost never played on the oldies stations.
Jimi Hendrix, Purple Haze.  For all you benighted qualia deniers out there.
Thelonious Monk, Blue Monk
Jimi Hendrix, Red House
Cream, White Room.  You say this is not a song of color?  What, is white not a color?
Los Bravos, Black is Black
Procol Harum, A Whiter Shade of Pale
Joan Baez, The Green, Green Grass of Home
