I like Abe with Lady Hillingdon or Peace :) He goes really well with pale pinks, too. It depends on what you like. He adds a warmer tone, so if you like that with your pinks, excellent. I do beds where I have all totally cool colors, and that's where I don't put him in.

Compassion is similar to Abe that way, imho.

La France has more blue tones than some pinks of that lightness/darkness. I like to play that up by putting her with violet-based roses. I think Blossomtime is supposed to have mauve tones, too, but mine did poorly in the winter and I still won't get to see her bloom for a while. Le Vesuve looks to have a lot of mauve going on.

Hugonis is a clear yellow, so he's useful anywhere you are looking for straight yellow with no peachy tones.
