The palette at the right is constructed by interpolating between
six images that are mostly a single color:
red, orange, yellow, green, blue, indigo. When painting in the
applet, the brush blends between two of these
images based on the angle at which you're drawing.
For example, if you paint directly left, you will get 100% of the red image, 60 degrees further clockwise, you will get the orange image. Painting at 30 degrees will produce a blend between the red and orange images. This was a one week assignment for John Maeda's Numeric Photography course that took place in the Fall of 1998. (Later ported without further changes to vanilla JavaScript.) << ben fry |
