What is a differet in effect from blending ?
If I need to get transparent color(in scene without textures) - what option should I use ?
You still use blending, look at nehe.gamedev.net tutor on blending.

Screen door transpareny is the use of glPolygonStipple patterns to mask out pixels in a dither pattern.
E.g. 50% transparent is a checkered bitmap, half of the pixels are not drawn.
Looks butt-ugly but works without depth sorting with full depth compare functionality enabled. Often used in CAD apps.
Thanks a lot about brief and clear answer!
