How to Create a Custom Palette File

1. Choose a raw image <NAME>_raw.png.
2. Using the raw image, create the linework layer <NAME>_line.png.
   • Soft edges are allowed.
     • If tracing, use the brush tool.
     • If using selections, turn on anti-aliasing.
   • The script only reads the alpha channel here; it does not use any color information.
3. Using the raw image, create the base colors layer <NAME>_base.png.
   • Hard edges are required.
     • Use the pencil tool instead of the brush.
     • For other tools, turn off anti-aliasing and feathering.
4. Using the base colors layer, create the color areas layer <NAME>_area.png.
   • Hard edges are required.
   • Different items/materials/areas should be different colors.
   • If colors match in this color map, they will match forever.
     • For example, if the hat and the skin are both colored #A1B2C3 in your area.png submission, then the hat will always be skin-colored in the Palette Editor no matter what.
   • If you're picky about color IDs, encode them in the red channel.
     • To match official color maps, reference the Palette Editor. Click on a sprite and you'll see the corresponding color ID as a circled number in the sidebar.

How to Submit

• Recipient: krazete@gmail.com
• Subject: [sgmpalette]
• Body: Attach the 4 layers: <NAME>_raw.png, <NAME>_line.png, <NAME>_base.png, and <NAME>_area.png.
  • Alternatively, instead of raw.png and base.png, you may submit a highlights layer <NAME>_highlight.png and a shadows layer <NAME>_shadow.png.
  • Also let me know your username if it isn't apparent. (Custom sprites are sorted into folders by username.)

I will input your submitted layers into create_sprite.py and upload the result here.

Please be aware that your submission may be denied, revised, or replaced in the future by me or another submitter without notice, usually for reasons regarding quality or redundancy.

Examples

All submissions are recorded in the custom folder of this repository.

Normal Submission

Raw	Line	Base	Area

Most submissions are like this, letting create_sprite.py do the work of extracting highlights and shadows from the raw and base layers.

Alternative Submission

Highlight	Shadow	Base	Area

The highlight and shadow layers are created by subtracting the base layer from the raw layer and vice versa respectively. Brightness and contrast can then be adjusted as desired to create more pronounced details in the resulting sprite.
