Color changes persist across unrelated outfits, and reset can turn previews/layers black #61

Summary

I found a color persistence/reset issue in Fashion Sense.

When I change the color of one dyeable clothing item in Hand Mirror,
unrelated outfits can inherit that color.
If I then use the trash/reset button, some previews/layers turn black.

I also see broken None previews for sleeves/shoes.

Versions

• Stardew Valley 1.6
• Fashion Sense 7.5.0
• Fashion Sense 7.4.0
• macOS

I tested both 7.5.0 and 7.4.0 and the issue still happens.

Repro steps

1. Open Hand Mirror.
2. Select a dyeable/custom-color clothing item.
3. Change its color to something obvious, like brown or red.
4. Switch to other outfits/items.
5. Notice that unrelated outfits now inherit part of that color.
6. Click the trash/reset button.
7. Notice that some previews/layers become black.
8. Check None sleeves/shoes previews and they may also appear broken or
   missing.

Expected behavior

• Color changes should only affect the selected item/layer.
• Reset/trash should cleanly restore the default state.
• None sleeves/shoes should preview correctly and not break the equipped
  appearance.

Actual behavior

• Color changes can affect unrelated outfits globally.
• Reset/trash can leave some previews or layers black.
• None sleeves/shoes can show broken or missing previews, and equipping
  them can also look wrong.

Notes

• I do not see content pack loading errors in SMAPI.
• I tested with multiple Fashion Sense clothing packs.
• The issue seems more like persistent color state / reset behavior than a
  content pack parsing problem.

I can provide screenshots and more details if needed.
