Please note that the final commit must be made after the latest changes and right before the merge. This commit should include the changelog updates and the app version upgrade. We need to either have a discussion to align on this or follow the established format used in the changelog file so far. The commit message should also follow a consistent pattern.

please use onSurfacePallet in text styles . according some part of material spec in this link.

Surface – Default color for backgrounds

On surface – Text and icons against any surface color

Examining Figma, we conclude that there is no consistent color for texts in light and dark mode, and there is a noticeable irregularity. Due to the need to temporarily fix this issue, follow the solution below :

Light Text Color : #242424

Dark Text Color #FFFFFF

Please add this color for color palettes (surface and non-surface) - if they are not available -
