I want to do an octant with semi-transparent panels with drawings on them. I achieved part of the desired effect, but the drawing is almost invisible against the white background, or when the other panels are semi-transparent too. I'm using "Blender Render" as the render engine.
Drawing visible when there is no transparency.
Drawing barely visible with the red panel semi-transparent (alpha 0.5).
Drawing almost invisible when all three panels are semi-transparent.
I'd like to have the panels semi-transparent (still showing their colors, but the image not so transparent). I think 0.5 alpha should give me a #808080 gray for the drawing, why is it becoming so white?
