Tri-Art Water Colours - Primary Magenta

Cerulean Blue

I love my Tri-Art colours but very disappointed I can’t get some of the colours I hand my students have come to rely on. This past year I have changed my supply list for my watercolour classes to include Cerulean Blue. I even talked a local art store to carry Tri-Art paints which they have done but now we are having a hard time getting Cerulean Blue. I put an order in this month and was only able to get 2 small tubes of Cerulean Blue. The art store is not able to get it as well and now I have to switch to another colour. Do I need to give up on Tri-Art colours as I can’t get the colours I like or will you have stock in the future.
