Red Venus

A couple of nights ago I observed Venus (according to star walk) with a weird, very deep red color. Usually it has a only a yellow tone, but this time it looked like a really strong red, almost like a LED light, I've never seen something like this before. Is this common? The planet was very close to the horizon so it might have influenced it's color a little, but I have observed Venus in similar conditions before and it never looked so weird. It was about 10pm.
