@Amanda Glover Hi Amanda! For sure! So I Turquoise is basically a Green leaning Blue that I love using. It is almost a green but still retains alot of blues, makes for an excellent color to balance yellow and red mixtures. Radiant Turquoise is basically Turquoise but it has White in it. So it serves as a good substitute for Titanium White when I am mixing something that calls for lightening of value but at the same time, also allows me to shift the color towards blue and yellow. Radiant Blue is basically a warmer neutral blue that has white elements, I use that as a substitute for Titanium White sometimes when I want to lighten up the value of something but at the same time push it towards blue without having any yellow interfering.
