[UI] - Allow Editing Previously Purchased Custom Colors

:bullseye: What is your suggestion?
I would like to suggest a quality-of-life improvement regarding the custom color system.

Currently, when adding a new custom color (which costs 1 Golden Plane), the color becomes permanently stored in the palette and cannot be modified afterward.

Even if a player is willing to pay again, there is no way to edit or replace an existing custom color — the only option is to keep adding more.

I suggest allowing players to edit or replace previously purchased custom colors.

:hammer_and_wrench: How would it work in the game?
A few possible implementation options:

  • Allow editing an existing custom color for 1 Golden Plane

  • Allow replacing a color slot for 1 Golden Plane

  • Alternatively, introduce a smaller edit fee (e.g. 2000 Silver Plane) for minor adjustments

From a UI perspective, this could be done by adding an “Edit” or “Replace” button when selecting a previously purchased custom color.

:balance_scale: Why is this a good idea?
Custom colors are a long-term and permanent feature in the UI, so providing flexibility to adjust them would significantly improve user experience.

Players may want to modify colors because they:

  • Slightly misjudged a HEX value

  • Made a small adjustment mistake

  • Changed their livery design style over time

  • Want to fine-tune an existing color

Currently, if a color is slightly off, there is no way to fix it — which can feel frustrating, especially since Golden Planes are involved.

Allowing edits would:

  • Improve usability and flexibility

  • Reduce frustration from irreversible choices

  • Encourage more use of the custom color system
