From doing some light research, cool colors, like blue and green, bring a soothing environment that helps you stay focused and be productive while warm colors like red and orange, bring creativity but also anxiety so I kept the warm colors on the more low key range. I love the tree stencils on desktops because it reminds me of growth, serenity, and opportunity so I chose a very cute and stumpy tree shape with colorful buds with miniature flowers sprouting for my desktop. I downloaded a set of brushes from DeviantArt and it's a really cute set by ploop26.
On top of that, I downloaded the free software "Fences" to keep my desktop organized, clutter-free, and completely clear of folders by just double-clicking.
Today has been a very productive day indeed!
