Maybe 3 min! Lucky I had leftover paints from another project today to use up. Hansa yellow light which i think is cool yellow. 

Would be helpful to list a few names of frequently used yellows as to which is cool or which is warm. Your class did give the tip of greenish or orangish guidance.  I still get confused.  I do have a variety of yellows such as cadmium yellow,  Indian yellow. New gamboge etc., auerolion. 

I love short classes!!

 

I added new gamboge which is warm?
