 +====== 2021-09-08 - shoe color ======
  
 +shoe colors? seriously? yes... but obviously not because of a shoe. interestingly,​ not quite about a color either... so let's start.
 +
 +some time ago i was asked by a friend of mine, what is the collor of this shoe:
 +
 +{{:​blog:​2021:​09:​08:​shoe_color.png|what color is this shoe?}}
 +
 +turns out that this was a fairly common photo sent around on the internet, around 1-2yrs ago.
 +
 +it's pink to me. but it turns out that many ppl see it as gray, instead. so it got me thinking...
 +
 +
 +===== 1st approach =====
 +
 +my 1st guess was that it's the same thing as with blue and green colors. the wavelengths of these two colors are next to each other, so around midway in between "​perfect blue" and "​perfect green",​ some ppl see "still green" yet others already interpret it as "​already blue". it's not so obvious however with gray and pink (not to mention shades), as these are not monochromatic.
 +
 +
 +===== 2nd approach =====
 +
 +these must be close to each other in color space, then! so let's see how our [[https://​www.color-hex.com/​color/​c4aead|pink-ish]] and [[https://​www.color-hex.com/​color/​808080|grey]] look like:
 +
 +  * "​silver pink" = 196, 174, 173
 +  * "​gray"​ = 128, 128, 128
 +
 +ok -- not exactly the same, but also not super far away...
 +
 +let's give it a shot in another color model, namely HSL/HSV:
 +
 +  * "​silver pink" = 3deg, 12%, 77%
 +  * "​gray"​ = 0deg, 0%, 50%
 +
 +now the proximty can be seen much better! only the last parameter is off by around 1/4.
 +
 +due to the above, there are some "​shares of pink", like [[https://​en.wikipedia.org/​wiki/​Shades_of_pink#​Silver_pink|silver pink]] that could be considered a bit more gray. thus the confusion.
