Yellow filters 21 22 23

So I generally used a light yellow for my black and white stuff.

Now for a new lens I scored a nice B+W #23 filter for a bargain. It's a "dark yellow"

I had a yellow and a light yellow jumping to light red and deep red.

Ideally, I want a light yellow MRC. Am I being too picky about it? The difference is probably minimal

What do you think?

I generally like keeping the light yellow for all my BW stuff. Would you buy an MRC #21 if you had a single coated 23?

ooo I like the 23. nice and strong for when I want the effect. Try it!

I like the 021 the most, but the 023 (equivalent to a Wratten #15) is awesome. Hold on to them, I don't think they being made anymore.
