Description Kia 2023-12-19 09:22:44 UTC 
SUMMARY
When I add a color to the palette, the hard drive use, and for some reason network spikes briefly. This causes a short lag and and unnecessary wear and tare on the hardware if my assumption is true.
The color palette has save/load options and the data is small enough that we can keep it in ram until the user decides to save the document or the palette. Fixing this will make the program feel more responsive and enjoyable.

STEPS TO REPRODUCE
1. Select a color
2. Add it to the palette
3. Listen to the hard drive (in case of mechanic ones) or check the task manager

OBSERVED RESULT
Lag when adding colors to the palette

EXPECTED RESULT
Smooth operation
