Need Help making pixelated color spectrum/pallet

Not sure how I would get this done but I wanted to create a 16x16 pixel tile color spectrum where each tile would be a uniform slice of the visible spectrum and not repeated.

The file would ideally be 12 x 40 of these tiles for a total of 192x640 pixels; 480 total color swatches spanning the visible spectrum but staying clear of the super dark or really light

Any help would greatly appreciated.

Here is one approach

- Start with a 12x40 pixel image filled with gray
- add noise filter set at 50% (uniform not Gaussian)
- Use image size by 1600% using nearest neighbor rendering

You could have fewer dark and light extremes by using less than 50% noise and/or curve adjustments etc

Here is a PNG version of the above process:
