For me, part of simplicity is cohesiveness, I want all the designs that i create for myself to look the same. My main way of doing this is by using all the same colors, stroke weights, outline thicknesses, and shadows. To keep track of all this i created a parameters page. In this page I document all the colors I use and all the extra stuff I add onto my designs
The image above is my current parameters page, along with what you see above also on the document are swatches that have not yet been filled. In my layers panel these swatches are labeled "Not Done" while the others are labeled "Done". The below image is what the whole document looks like and there you can see all the "Not Done" swatches. The Typeface that I used for the labels is "Clepto" I came across it while doom scrolling and thought it looked nice so I saved it where it sat for months before I went into my "Typefaces" folder on Instagram looking for a font and found it again.
