I'd convert the color HLS array to RGB, for sure. 
As to the fastest way to create the array, I'm
not sure I can decipher how a 8192 vector
relates to a 512x512 array. (Except to note
that 8192/512 = 16.) If you can reform the
vector into a 61x512 array, then some kind of
array sub-scripting of the larger 512x512 array
will surely work.

Cheers,
