I finally changed the color spiral map to follow a logarithmic spiral path. The effect is simply great ! At high iteration count, the edge of the set gets more sharply defined but there is a large variation in the number of iterations required for escape while further away from the set this variation is almost linear. With the linear color map, cranking the iteration count would yield a better defined set but only a small portion of the edge near the set would receive most of the color shades. With the new progressive color map, the edge near the set receive color shades that progress slowly while the parts far from the edge end up with fast progressing shades. Take a look at it in action: the old color map has only a few colors far from the edge while the progressive map spreads the colors evenly across the whole image.
