Add other themes

[AyushSaini00]

You can add any theme you have in mind, but for starters, you can pick from theme/colors from any of your favorite apps.

To add your new theme, locate theme.js and then add your theme changes there. Also, add your theme name with the reference link in the README.md file as well.

Things to keep in mind while adding your changes:

• make sure you are adding the hex value of the color (for eg: if you want to add black color then add #000000 instead of black
• please make sure all the hex values are in all caps (for eg: add #FFFFFF, not #fff or #FFF or #ffffff)

May I try this one? I have a couple of theme/colour sets I'd like to add.
