I thought it would be interesting to invert the idea of showing only the dominant hue, and show everything but that instead. I used the exact same code, but inverted the if statement so:
if (!hueInRange(hue, lower, upper))
if (hueInRange(hue, lower, upper))
Effect is as follows, as with most of these, my favourite effect is on the painting – does it work better because it is a more studied use of color? I’m going to make something that will compare and contrast the effects, and allow me to loop through pictures so I can look for interesting results.
