how to scale my color's RBG in 0-255?

wangy

There is my code, but my color1,2,3 can be bigger than 255 and less than 0, how to fix it?

and when I run the program, there is a solid black ellipse in the center even if I don't press my mouse. How can I erase it?

Please don't post screenshots of code.

Instead, paste the code itself so that people can read/test it, and format it by highlighting your code and pressing Ctrl+o. https://forum.processing.org/two/discussion/15473/readme-how-to-format-code-and-text

You can use colorMode to scale color to any values.

e.g.

colorMode(RGB, 0, 500);

or use constrain to constrain a value to 0..255 range

or map() to convert from one range to another.
