White Xmas (?)

from Michael’s   Visual Phenomena & Optical Illusions


What to see

Two Christmas trees, and bars – is the colour of the two trees identical? To me the left one looks a little more yellowish, what about you? The topic of interest here: the two trees are absolutely identical in their colour. All in all, there are only three (3) different colours in the picture. Deselect the checkbox Bars/flakes to convince yourself.

What to do

With the Pop-up you can switch to Snow rather than Bars – possibly more appropriate for winter season, but a markedly weaker effect. You can also change all colours to your liking. The Radius of the “snowflakes” has little effect for me.


This is a seasonable variant of colour assimilation.
