I have a portfolio: https://vulcanwm.is-a.dev and I've seen many portfolios with a Skill Set List.
I want to implement that in my own portfolio, with each skill being a different colour. The colour will represent how long I’ve been using the skill for (eg. Green for 3+ years, Blue for 2+ years).

Should I add a skill set to my portfolio, and if I add it should I add the colour system to it too?
