Colors not in our visable Spectrum

[Hyperspaceblastoff]

I always read trip reports about people seeing colors theyve never seen be4, is it because their tripping and forgot theyve seen those before, or becuase their mind creates those unatural colors, or becuase ur puils are dilated and you can see colors that actually exist but cannot be normly seen with the human eye. What drugs do you think show new colors? i hear mescaline, dxm, and acid do this. Also when your pupils are dilated can you see more stars in the sky? like as if there was less light polution?
