I have run the images through pngout to bring down the file size significantly. I also went and organized them in what I hope is a logical order. (modified light spectrum order)
Note: The old "small red" and "small blue" have been renamed to "alt small red" and "alt small blue"! If you were using these two markers in macros, and wish to keep the same look as before, please update your macros.
The new markers have thinner borders.
