Recently, my team and I decided to redesign the site (https://theoptics.org/) and I volunteered to start redesigning it (I don’t want to spend money on a designer, and it’s time to study Photoshop by myself).
I decided to start the changes from the new icons of our site, but a problem appeared immediately . When I start painting over blank areas, such as a T-shirt or fingers, some areas remain unpainted. At first I used a "paint bucket tool" in order to spend less time, but because of this, the thickness of the icon is reduced. Tried painting with a brush but it takes a lot time. Tried using the "magic wand tool" to select these areas and fill them further, but the "magic wand tool" is completely unpredictable and I can't edit the selection it makes.
So tell me, please, can I somehow quickly paint over the areas? What tools can I use for this?
Success consist of going from failure to failure without loss of enthusiasm
