Particles 2D and 3D - fix hue variation not working by transposing the hue matrix

Browse source 
The hue variation matrix is hardcoded as transposed and thus the multiplication always yielded the original color value.
I wanted to keep the matrix and get the same result by switching the operands (getting a result as if the matrix was transposed).
