I have used regular Cadmium
I have used regular Cadmium Yellow before, but it has a warmer value than the Cadmium Yellow Light, and this pigment gives me purer mixing of lighter greens, mixing with cobalt making teal this yellow shines out, and also goes a lot further than other yellows, mixing with white this yellow makes a vibrant highlight seem to glow. My fades in an eerie sky are easily made using cobalt blue and lead white, the teal mix seems to have a better life than with any other yellow, adding lead white and letting the color do the work.
