If you switch to 1" squares, the sky is the limit for color.

But hex seems to come in two shades of black and white.

You will not find "loose tile" one inch anything. Increase the size limitation, look in the honed marble category of hexagon mosaics. A Google of "colored honed hexagon mosaics" will get you hundreds of images as below link, and all still obviously sold on mesh backed sheets roughly a foot square give or take. In MANY colors .

Remember too however, that the reason these mosaics are so black/white or tonal in nature, or a single color, is that the size alone, plus grout, is usually "busy" enough, so plan carefully and VERY carefully with regards to thickness and your pattern.........: )

Why not check out the cement tile instead it won’t be a personal pattern but honestly a much easier install and the look is awesome
