Xmas Colours

from Michael’s Visual Phenomena & Optical Illusions


What to see

Two Christmas trees, partially covered – 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 (green, blue, yellow as default). Deselect the checkbox Bars/flakes to convince yourself.

What to do

With the Pop-up you can switch between Snow and Bars. Snow more appropriate for the winter season, but a markedly weaker effect. You can also change all colours to your liking.


This is a seasonable variant of colour assimilation.
