Create for me 3 logos with the main features being a circle with the first logo

Create for me 3 logos with the main features being a circle with the first logo having the color blue and white and the second logo whose color is red and white and the third is black and gray. I want you to make a logo that is a circle made as if it were made by a brush but I want it to be a circle that looks like the crescent moon but about the colors I mentioned I want you to make the colors as if there was a gradient separating the color of each one.
