You really can't judge them by the color that they look to your eye. I don't think that anybody makes a lower contrast filter than Ilford 00. They all pretty much work with all the different paper brands. You really have to try them out to see what they'll do with your paper choice and your enlarger. I'm still using my set of DuPont (Yup, they used to make paper! Chemicals and film too a long time ago.) Varilour filters that I bought in 1968. They seem just fine with Kodak, Ilford, and used to work OK on Ansco VeeCee. I'm printing with an Omega B-22XL with a 50/2.8 El Nikkor and an 80/5.6 Schneider Componon.
