Is there a Red-Yellow-Green colour scheme that works?

Hi all,

I have been tasked with creating a chart that uses a "traffic lights" (red - yellow - green) colour scheme. Despite some suggestions of alternatives (including Red-White-Green), and explanations for why they might be preferable (colour blindness, perceptually uniform), it has to be RYG, and this isn't a hill I'm going to die on.

So, has anyone found a Red-Yellow-Green gradient that looks good?

I use RColorBrewer in some of my work.
You can play around a little on their website also
