Three paintings, one color scheme

What can I say? I churned them all out pretty quick, so that happens sometimes.

"This painting brought to you by the letter H"

"It's a painting of a flower, stop thinking so hard"

And this last one I haven't named yet, though I did upload it to a few places with the caption 'squarish things in squarish things' so I might end up calling it "Squarish" or "Ish"
