I have started adjusting tag colors to match emotions that i often feel when dealing with a particular kind of task.

For example I enjoy camping and hiking. I use the words hiking, camping, campingsupplies, etc for my tags. I also change the color of those tags to blue. I do this because the color blue is restful to me. These tags catch my eye easily.

I did a bit of research regarding various colors that correspond to emotions. Here is a link to a helpful article: https://thelogocompany.net/blog/infographics/psychology-color-logo-design/

I have found that colors really are a personal choice. So you may need to tweak your color choices. The colors of tags are easily changed in RTM. Look for the pull down button by each tag and you will see various colors.
Thank you RTM!
