What is it about red and blue?
So what? — In addition to causing a depth effect, chromostereopsis can also be annoying and hard on the eyes. It is fatiguing. Although there are different theories as to why your eyes react to these color combinations in the way that they do, the important thing to remember is that they do.
What should you do about it? — If you are a visual or web designer make sure that you are not using red and blue together in this way. I still find web sites that have this color combination. Here are a few!
What examples have you found?

[…] What Makes Them Click » Blog Archive » 100 Things You Should Know About People: #9 — Chromostere… When people see different colors close to each other there is the possibility of an effect called chromostereopsis. The depths of the lines appear to be different — one color jumps out and the other color recedes. This is most prominent with the colors red and blue, although it can happen with other colors as well: (tags: color websites screen) Leave a Comment […]
Thanks for making a point of how difficult red and blue is to see. I have red-green color blindness, and it seems worse for me (maybe not). I still see so much of this that I thought it just because of my color blindness.
Very interesting.what R the best combinations?
Many flags have red and blue side by side. I wonder.
red on blue on information display… Flag eh?.. i wonder… i wonder…

Yes, massive chromostereopsis but this website is also just heinous.
I agree. It fealt like a “used car salesman” website lol!
Argh, they hurt my eyes.
Actually, a good rule of thumb is to go with heraldic rules. Under medieval heraldry there were two “metals” – white (silver) and yellow (gold) and five “colours” – green, red, blue, black and purple. The rule was that you never put a colour next to a colour, or a metal next to a metal. The principals are still largely adhered to in flag design to this day, with some exceptions.
*cough* principles, not principals. *cough*
Brickie — interesting history about the medieval heraldry. I hadn’t heard that before.
What are the best combination colors? Any one ans this? if so why?
The main thing if you HAVE to use Red an Blue, is to use NEUTRAL “colors” as separators or “white space”.
White works great, so if you have literally WHITE space, the red/blue combination won’t be so annoying as if they were placed together.
The company I work for has red and blue as corporate colors and I hate it. But the use of lots of white helps reduce the problem.
Personally I would not use colors so bright and vivid together.
[…] “I can’t believe they did that!” I muttered to myself. Red-on-blue is hard on the eyes and should be avoided in any kind of web-design and that goes for elearning courses […]
If you are a visual or web designer make sure that you are not using red and blue together in this way.
