Hey! No use beating around the bush.
I've attached everything you'd need at this link to make your own colors for Aerith DE. I'll allow each patron to submit one that I'll include in her final color set, and I'll try to include as many as I can depending on what limitations there are.
Read on for instructions, but if you already know how to use this generator, then send your finalized color swaps here. You can also submit what you've made to the patrons-only channel on my Discord.
Here's all of the palettes Aerith has now:

To get everything set up on the page, first click "Choose File" and upload the base color image, aerith_base.png, which I've attached to this post.

Then, copy and paste the contents of color_edit.txt (also attached to this post) to the text box on the left.

At that point, the page should look like this:

Click on the circle next to "2 unnamed color palette", under alt palettes, and Aerith should turn green. This means everything's working!
Do not edit any of the named color categories under sprite's palette! These are the reference colors that are taken from the base image, and are not what you're looking for.

From here, you can click on each of the boxes on the right-most side to change each of the colors. Each box represents one of the 8 color categories, and you can switch between the two default colors to understand where everything goes.

Once you're happy with your color palette, you can simply copy or save the color-swapped main image straight off of the website, and submit it to this Google form-
Afterwards, you're done! You're free to continue making colors if you'd like, but only the last one you've submitted will be used. There isn't a formal cut-off date, other than when I nebulously finish working on Aerith DE. Just don't spam, obviously, don't submit anything inappropriate, etc.
Also, you can send them in the patrons-only channel on my Discord! Just be sure to link Patreon to your Discord account so you can reap the benefits.
