Question

Graphic arts

There is an equation of 5 variables (x,y,r,g,b). Need to draw a 5 dimensional graph (point (x,y) will be painted in (r,g,b) color)

Answer 1

Take and draw.

Answer 2

I suppose we need to draw not a five-dimensional graph, but a three-dimensional projection of a four-dimensional projection of a five-dimensional figure.
