Hello friends,

I have been messing around with color palettes a lot lately, trying to mix colors effectively etc. I came across something interesting in this red purple color (R:125 G:0 B:44) (H:339 S:100% V:50%).



When it's put next to some other colors, it creates the illusion of an embossed edge. The effects comes from the red hues and works with colors of a full saturation and mid value. Its really only effective against the lighter blue hues and the bluer greens, when the greens become to yellow, or the blues to purple it starts to disappear.

I assume this is some kind of monitor artifact, so i tried it on the only other monitor I have and It looked the same. Can you see it? Whats going on?

On my left monitor there I cannot see any emboss whatsoever. On the other one, it feels like there's a very subtle black gradient on the right side of the red pixels.

It's an artifact of LCD sub-pixels.
It's easier to explain with a picture so hold on while I make one...

OK, here we go.
Here's your monitor displaying white:


here it is displaying red:


and blue:


and here's what happens when saturated red and blue are displayed adjacently:

it creates a gap!

The effect should be easy to notice it in the "white" explanation picture as well.

And this is why LCD and similar monitors suck.

(Note that this only really happens in native resolution)

On the right side it also creates a whitish border.
