After generating intermediate values of the 64-bit FNV-1a hash algorithm for a side project, I noticed that the lowest 3 bytes created a tiling pattern with a gradient from bluish green to reddish orange as y increases. This does not occur for the deprecated FNV-1.

Each pixel color is represented by:

{ (xor(y, x) * 1099511628211) % 2^24 | x ∈ [0, 256), y ∈ [0, 2^24) }
