Zeta Lyrae colors

Anybody else see this pair as anything other than yellow?

By contrast, note that our yellowish Sun has a definitely 'redder' B-V of 0.656, which we have evolved to consider as white, at least during the day. A B-V of 0.28, not to mention 0.19, is decidedly bluer than sunlight.

I found a sketch that is quite close to how the stars appeared to my eyes and seems to show that other have perceived this pair as yellow and bluish.
Real or imagined, the colors of doubles are a relaxing way to pass some time in a light polluted back yard (which a nearly full moon served to only make worse :-) ).

In my experience colors of stars show different in different scopes.

It's a color image by the way.

Zeta Lyr is a binocular double star but I don't remember ever to notice colors.Something to check.
