| From now on, my HN top color is International Orange.

| Interestingly, the bright yellow color usually means accident,
| while orange means regular decompression stop. I have seen pink
| ones but they seem very rare.
|
| So I'm guessing people must think yellow is more visible?

|
| Orange for surfacing and yellow for an emergency, as you
| describe.

|
| It a shame that CMAS, PADI or SSI don't propose a standard.

| So did I, so I wrapped my car orange:

| Great job :)

| What purpose does it serve to break the back button?

| It works fine on chrome and firefox for me

| The back button also breaks for me on macOS Safari.

| Are these orange colors easily recognizable by color blindness?
| fwlr wrote:
| When it comes to colorblindness, it doesn't make much sense to
| ask if a single color is recognizable. Color blindness is a
| difficulty in distinguishing between different colors - some
| pairs of colors that are visibly contrasting to normal sight
| may not be visibly contrasting to colorblind sight, such as
| red/brown, brown/green, and red/green.
|
| There are three main mechanisms of colorblindness,
| corresponding to the three main types of light receptors in the
| eye: deutan (green-weak), protan (red-weak), and tritan ("blue-
| weak", although this is not a common term). About three
| quarters of color vision issues are deutan, one quarter is
| protan, less than 1% is tritan.
|
| When you go out into the world and start interacting with
| contrasting color pairs, both green-weak and red-weak color
| vision cashes out as "red-green colorblindness", while blue-
| weak cashes out as "blue-green colorblindness". None of these
| have issues distinguishing yellow/orange from blue.
|
| Presumably this is actually the motivation for the
| international air safety color being orange, as it's easily
| distinguishable from blue sky.

| Why is International Orange (engineering) red instead of orange?
| yreg wrote:
| How do you define the line between orange and red?
| CUViper wrote:
| If pure red is at 0deg hue, and orange at 30deg, then that
| engineering value at 3deg is much closer to red. The other
| two at 18deg and 19deg better fit the reddish-orange
| description, still more orange than red, while safety orange
| is up at 28deg.
| TeMPOraL wrote:
| I'm going to guess it's path dependence, as usual: that
| 3deg hue is called "orange" because it came from iterating
| on other hues that were more orange.
