Try Mars? Not a star, duh, but it's glaringly red, even when observed in the city.
Mars is particularly bright right now too, it's quite striking.
It's just after full Moon and Mars is just next to the Moon, hence also on max luminosity.
I've got mild red-green colorblindness (less severe than the author's); this article is great, and goes into much more detail than I knew beforehand. If I could add some suggestions to the author's at the end: * First, if you have the option of using one or the other, do so. Like, you can use red, blue, yellow, purple, and black for lines on a graph before you even need to find an additional color like green. * Secon…
How about this for selecting. Colour scheme: just display a colourblind was test and ask the user to select the one they can or can't read. Then you don't have to rely on them knowing what the different types are at all.
I'm red-green colorblind but the only way it noticeably affects my life these days is with the icons on Github's notifications page. A merged PR an an open PR have different shapes and the merged PR is blue and the open PR is green --- very easy to distinguish. But an open PR and a closed PR have identical shapes and are only distinguished by the open PR being green and the closed PR being red. Or so I'm told anyway,…
>> Maybe I can help you understand how that impairment—and it is an impairment, however mild... This is actually a slightly controversial claim. While r/g color-blind individuals do have difficulty viewing colors, they seem to have an easier time seeing through camouflage: A study on the ability to distinguish tones of khaki: https://www.discovermagazine.com/mind/in-combat-stick-with-t... There is strong anecdotal ev…
Well, there used to be jokes about stupid women seeing non existent color differences and making big deal about them. As in women being crazy and their husbands rational having to deal with that. Meanwhile, color blindness in overwhelmingly make issue.
I had a woodshop/electronics shop teacher in high school with severe red/green blindness. He said at stop lights the only reason he knew which was green and which was red was because of the layout. But when he went to states with sideways lights, he'd just wait until the people behind him honked until he figured out which was red and which was green. But as an electronics teacher, it was extra problematic, because re…
I'm r/g colorblind, and suddenly the indistinguishability of small colored objects makes sense now. Wow. Okay then. I hate multicolor LEDs with a passion. Those little amber or green dots look identical to me, even when you put them side by side. I use a phone app that uses the camera and shows me RGB values at a reticule. I've gone through rack and racks of equipment with that app, looking for things like dead drive…

I have also red-green color blindness and it makes me really mad that a lot (like 90%) devices have a tiny LED that indicates if it is charged and the LED changes color from red to green when it is fully charged - I have to ask my kid or wife what color it is. Please please, if you work in hardware, make it a red/blue or green/blue colors for empty/fully charged, or make it blink, anything, just not tiny 1 pixel size…
Turn off light when charged, works for Panasonic batteries charger.

I think the visual design should embrace both shapes and colors, and use color palettes that are discernible for people with different senses of color.
The objection is usually that the design must look "neat". I'd say that a visually neat but unusable design wastes all the effort that went to making it neat anyway. Being bold and even flamboyant in order to be highly visually discernible pays off most of the time; look at flowers.
Yup. If I had a pound for every time someone would hear I'm R/G colourblind, hold up something red and go "so what colour is this then?".
