[Accentuating a Colour]

That's exactly what I was trying to achieve, thanks. I thought their might be a different method (rather than having to pick out individual parts), but it still works.

[Accentuating a Colour]

Hi everyone, I'm a new member and I need some help.

I'm wondering if there's any way to accentuate one specific colour, while making the others black and white. Here's an example of the effect I'm trying to achieve.

Any suggestions?
