I've had my K-3 for more than a year. When I set up my new K-S2, I noticed that it had many options for menu display color- cool. I just got curious and sure enough, the K-3 has that, too!

Oh yeah, even older cameras have a couple. The red one is good for low light shooting

Tool 1>Lcd display>Display color. But I think you have already found it.
I use blue, but I may try the red option.

I'm using green to fashion-match my green K-S2. And red or orange on the K-3.

I have my K-3 set to red and my K-50 set to blue so I don't get confused. Sometimes it works.
