Blend modes

[benjamminf]

Perhaps an ability to use blending modes? Usage could be something like:

var color1 = Spectra(...);
var color2 = Spectra(...);
var blended = color1.blend(color2, mode);

Where mode is the name of the blend mode as a string.

Looks good - do you want to implement these?

[benjamminf]

Now that I think about it, it might make more sense to specify each blend mode as it's own method.

color.dissolve(...);
color.multiply(...);
color.screen(...);
...

But I'll give it a shot.

That sounds good. These are kind of like variations on mix so they really should be different functions.

[benjamminf]

Yeah exactly what I was thinking.
