Are you talking about a generated image or a real scene?
And how are you testing the colour?
Eg, if it is a real scene, did you photograph it and test the pixels?
I don't know my way around OpenGL, but if it is a generated image then I
would guess that you have a setting wrong somewhere.
But from your previous posts, you look fairly new to OGL and you're
talking
about raytraced reflections??
Anyway, It doesn't make any sense to me.
I can't see it being an optical illusion as Fungus suggested.
To get a colour ****ft toward blue, you would have to have a lot of yellow
showing for your eye to 'want' to see the opposite colour.
But you are saying 'plane', so I imagine that the whole surface is looking
blue?
The resulting colour should be somewhere between yellow and green
depending
on how reflective the surface is.
