Simple Color Range Multi-Select Noodle

Simple Color Range Multi-Select Noodle (or SCRMSN, pronounced: "Scrimson") is an Aseprite script that allows you to quickly add, subtract, and replace colors. It was inspired by the built-in color range selection tool: select -> color range. However, unlike the built-in color range selector, you can continuously add or subtract more colors as you go. No need to return to the select tab a million times over as I used to... (*Cries*)

SCRMSN works off of the principle of a foreground color change listener. Use the color picker tool to grab colors. If you're in the "Adding" selection mode on SCRMSN, then every change in the foreground color will add a new color range to the current selection. If you're on the "Replacing" selection mode, then your previous selection will be overwritten with the new color range. If you're on the "Subtracting" selection mode, then every color range you click on will be subtracted from the current selection.

There are also tolerance weights for the 4 rgba channels. (This script only works in rgb mode as far as I know) Each weight adjusts the sensitivity of that channel. A low value means more selection than normal. Think of the weight as a percentage: if it is at 100, then you will see a normal amount of tolerance. If it is low, then Aseprite will be more tolerant of color differences in that channel (leading to more selection). I designed this with the alpha channel in mind since it never made sense to me that a difference in transparency counted for as much as a difference in red, green, or blue.

Note: 

• The code may run a little slow on large canvases. It is running through and doing a pixel-by-pixel tolerance check and computing selection edges.

Have fun ripping all those art assets doing legitimate pixel art.  

May the noodle be with you!
