Popular Solder mask Colour Seeed poll

I learned something.. I did not know that green actually performs better.
Not that I would ever need a 4mil wide mask but interesting "fun fact"..

I use black solder mask at work for all the boards I design (because of visual aesthetics only)..

Are any ICs available in different colours? I came across some white DIP package ICs the other day there and thought they were highly unusual.

I've only seen ICs in black and white. White is far less used than black, and almost all of the white chips I've seen are opto-isolators
Hmmm. Now that you mention it, the one and only white IC in my collection is indeed an optoisolator. Wonder if there's a reason?

There is many transparent ICs too. Mostly when portions of the guts have optical sensors. As beam shape sensors in optical drives

Two of them at the lower branch :

For focusing :

Mice use them also.
