Apple Bold in ROYGBIV
Apple Bold is a wallpaper pack that features 7 individual wallpapers in colors Red, Orange, Yellow, Green, Blue, Indigo, and Violet, or ROYGBIV and a Rainbow-ized wallpaper itself. I used these colors because they are the 7 colors of the Rainbow.
You will download a total of 32 wallpapers; 8 wallpapers in each size.
You can also get these in Grayscale.
