weighs the color against the background / surrounding colors to get you something that feels just like the color you chose it from.

Needs:

• original color
• original background

then it makes...

• new color built to work with the...
• new background [defaults to white?]

[√] implement it!
figure a good UI to do the following

• undo a recoloring (and only that one)
• apply the recoloring only when ready
• apply multiple recolorings from a few slices
• need a history of recolorings, so can delete one or change it and then all the recolorings are re-applied to the original. this is the only way to support undo-ing and all that.
• what to do when a new image is dropped in? nothing! but then include it in the next recolor? or try and treat it as a separate "layer". Do i really want to implement layers? No.

possible fix:

• iterate over image once to find the min-Y and max-Y, then divide that space into buckets.
• hack: re-run the algorithm with more and more buckets until you've got as many colors as you want. binary search lol

example:

some feedback: when I wrote change white to blue, it ignored the obvious white shirt and instead made the skin blue!!! very strange. But I know you are working on this. Colors as one can see, are hidden within other colors; yellow is in orange , etc so how would one differentiate as one works on a photo to change the colors? Ex: I ordered it to change yellow to blue and all the trees turned blue!!! It's fun though!! Love ya, mom

• √band of color behind every saved color
• use stylus or similar to mix the colors w/ darken or lighten
• allow formulas or sth, like a spreadsheet of colors
• sample 4, 8, or 16 pixels averaged instead of just 1
• lighten and darken buttons
• invert button next on the swatches
