only in v1; v2 changes it to "others are chosen to allow the most accurate perception by as many viewers as possible"); as far as I can tell this hasn't been published yet. There's also "Domain
Coloring and the Argument Principle" which says on page 4 "Before we go on, however, I should admit an obvious disadvantage of this technique: Not everyone sees color the same way" (but doesn't explicitly talk about colorblindness). A third mention (by the same author) in "Creating Symmetry: The Artful Mathematics of Wallpaper Patterns" says that "I have taught this material to students with limited color vision, and it seemed to work when they designed their own color wheels made from tones that they could easily distinguish." I'm not adding these references myself since I'm not sure how good they are, but I do think the information belongs in the article. (

I think the color-blindness claim is fairly obvious, but I haven't been able to find any perfect sources for it. The closest I found is "Visualizing modular forms" which says on the first page "While many of these are purely aesthetic, some offer color choices friendly to color blind viewers" (but

The French description on the image explains it. Google
Translate says: "The color (hue) represents the argument of the function. The black and white lines (saturation, value) represent the values of the constant modulus function. This file has 4 layers: the white lines indicating the iso-argument

There seems to be an bit of a war going about some content that would expand the scope of this article a bit, but no discussion here about it. It looks to me like a compromise would be in order, if the new material is sourced. I'd be happy to look at it, but don't want to chase it down across

gets along fine without mod, and we all refer to time without saying something like "I get up at 8 a.m. mod 24". So we don't need to introduce mod for this topic. Are there any objections if I create an image without "mod 2π" removed for use in this article? —
324:
Self-linking aside, I think that 3d extensions to domain coloring are (or should be) beyond the scope of this article for the following reasons: one, most visualizations of domain coloring are expressly 2d, two, we're not talking about
Kaehler manifolds here
1062:
I like the explanations next to the coloring diagram, except for one detail: Of course it is correct to consider the phase as a congruence class, but I don't think this concept is necessary to understand the article.

260:
Is it necessary to mention
Riemann surfaces in this article at all? It seems that it has nothing to do with domain coloring. Maybe add a section on other methods of visualizing of complex functions?
1125:, there are white lines (for argument), black lines (for module), and then there are smaller lines, in the background. Can anyone state what they represent ? I believe it's missing in the article

I corrected the unit circle image. Previously the legend for the phase of cyan said "2pi mod 2pi", which was incorrect. I changed it to "pi mod 2pi", which is correct

The pictures look nice, but for sin(x), why does the color change along the line im(z)=0? sin(x+0y) is real, so shouldnt it be red all along this horizontal line ?
1153:, the intensity variations representing the module, the color representing the argument". I'm not an expert on this, but that seems like a correct explanation. --

sin(x) is real indeed for real x, but it can be either positive or negative depending on what x is, so the argument of the value varies between 0 (red) and
