Hi! I wanted to ask if it’s normal that the edges of my brush strokes look darker than the middle? Here you can see it happen especially with the light green but also the ochre in the sky. I’m using Rosa Gallery pans on Arches hot pressed paper (100% cotton, 300 g/m2). I don’t really like the look. Is there a way I could avoid it?
