Hey @mnkth01a, thanks for contributing to docs, although this entry is missing some crucial things and needs changes -

• Please remove .vscode/settings.json; it is not related and is not required here. The PR should only include file changes related to concepts.

• Please remove the new file you have added, terms/colors/colors.md, as it is not required. You need to make the edits in the existing file, concepts/colors/colors.md.

• Only add the requested sections in the issue, do not delete the pre-existing text.

• Please ensure that the color snippets are loading in Markdown as per your screenshot—I can't see that in the GitHub preview. Also, please don't use URLs from some other unknown website.

I am closing this PR for now, but could you make the changes and then open it again for review? Feel free to let me know if you need help. Thanks.
