--description--

Given two buckets of paint, each with an RGB color and a fullness level, return the mixed RGB color as an array of three integers.

• Each bucket is an object (JavaScript) or dictionary (Python) with a color property (an array of three integers [r, g, b]) and a fullness property (0–100).
• The mixed color is a weighted average of each channel in the two colors based on fullness level, with each channel rounded to the nearest integer.
