Thanks so much for the kind comment! You can find the answer of your question at example2. Great code.
Q. What do the different 'colours' of noise do?
Very helpful. I have one question. This functions generates the noise samples irrespective of SNR values. How can I do it?

Explore music. Zaru A blistering marriage of blackgaze and screamo, this ranks among the best "black metal" records of the year.
Favorite track: everyone goes away eventually. Left: our staged per-tile optimized scrambling, applied to a Sobol sequence of sampling points, produces a power spectrum close to Blue Noise. Right: Rendering of a challenging scene featuring depth of field and high specularity jewels. The sampling was done with the Sobol sequence top and our sampler bottom ; both use samples per pixel and 3 light bounces.
Blue noise property test
Note the improvement in aliasing when using our method in comparison to the original Sobol sequence. Abstract Distributions of samples play a very important role in rendering, affecting variance, bias and aliasing in Monte-Carlo and Quasi-Monte Carlo evaluation of the rendering equation.
