Outreachy Task Submission - Color theme with the main color as default

[Perpy-del]

This is creating a color theme that enables those with different perception of colors, keeping the one we have presently as default, but also adding a dark theme such that the parts with brightness would be a bit dark to enable those whose sight are affected by bright lights be comfortable with the application. This is so that the website is accessible to all. I would be grateful if this issue is assigned to me if accepted.

I am also eager to work on the color theme with maintaining the perspective of what Ushahidi is and with a suitable balance of dark and light themes. I am eager to work on this create pr for this and be an assignee of this issue.
