@Tsudhishnair _a please use this URL to review. I have built a custom component to help with the PR review.

Here, I have used all the colors provided by the GitHub labels color palette by default. I have added a color picker to test it with different colors.

Light mode

Dark mode

• Here, all the colors look good in the dark mode. The lighter colors do not look good in the light mode.
• GitHub uses a different set of colors for light and dark mode. Hence, the labels look good in all the cases.
• It can be observed that all the colors look good for "solid" type in both the themes.

@Tsudhishnair please have a look at the UI and LMK:

• If any further changes need to be taken up for the UI (different calculation).
• The list of colors that would be the best fit for neeto-tags-nano.
• Any other suggestions.

@AbhayVAshokan _a, as discussed on the call, let’s remove the new color prop and use the existing style prop instead.

As per the discussion, I am closing this PR. We will add new styles as part of the Tag component and the colors will be added as new styles.
