An example image of the digital art of the beans.

Description of this creative coding colorful beans.

It's the digital art of color-changing beans placed on the matrix. It was created by the creative coding code of the 'Processing'.

I've been learning about the color harmony law described by Deane B. Judd. And I tried to apply 'Hexad' and 'Intermediate' color palettes in this digital art.

I drew color gradation with many ellipses that have low alpha values.

An example image of color gradation.

This code does not display any images on the screen but generates image files in frames directory.







The 'Processing' code example.

Please feel free to use this example code, if you like it.
To see other works based on my code is my pleasure. And my honor.
