Is my blue your blue?

Test your color perception with this interactive test.

@jenbanim My test-retest results were 185 and 184 due to a slight ambient light change where I am. Camera colourimetry used to be part of my job in telly, and this result tallies with my observation that my eyes 'liked' blue pictures.
@Shifty176 @jenbanim I get about 185 if I use 'green' to mean "not blue" and 175 if I use 'blue' to mean "not green". My colour perception (as a protanomalous trichromat) has a band between blue and green - 'cyan' - that's very much neither but almost indistinguishable from white.
@kim @jenbanim when I got my job initially, there was testing because 'normal hearing and colour vision' were a prerequisite. Over the years, I came to spot that I had a blue bias, in which colours that some racks engineers described as green, I described as blue. It didn't matter, as the vectorscope was always right, and as long as people weren't blue or green, you could get away with anything!
