why do colors seem to appear in different planes on my LCD screen?

When I look at an image (on my LCD computer screen) that is composed of a combination of solid colors separated by black borders, I perceive the colors as appearing on different planes of depth, as if the image were three-dimensional. If I close either eye, the illusion collapses. Am I the only one affected by this, or is it a consequence of the way LCDs display color?

To attempt to illustrate what I'm talking about, I created a GIF that, to me, strongly produces this effect (no visual trickery involved):
I perceive red, magenta, orange, and cyan to be closer than blue, yellow, and green. Red is always closest, blue is always furthest, and green seems to fall exactly in the middle.
Can anyone explain to me why this is, and if you can even see what I'm seeing?
