Color scheme red-green not workin with method gray

[cmahnke]

Calling this:

stereoscopy.create_anaglyph((left, right), color_scheme="red-green", method="gray").save(rgAnagFileName)

Results in the following:

Shouldn't the background be white / gray, like calling without the color_scheme param? That is just green where the are cyan parts without the color_scheme param.

After searching for example it seems that the orange tint is actually to be expected...
Can anyone confirm?

I'll have to find my red-green glasses again, probably packed deep in some box somewhere. It's been a while.
