Sennelier Watercolour S1 Lemon Yellow (501)

This Hansa yellow is transparent. It has excellent brightness and tinting strength, and its drying time ranges from average to slow.

Hansa Yellow makes more intense tints and cleaner secondaries than Cadmium Yellows, especially when mixed with other organic or modern colours like Phthalo Blue and Green. Because they are more transparent, they have great value as glazing colours.
