Description

When rendering contour-type charts, I want the colors of the contour lines to be customizable via a user-defined array (similar to a colorscale) instead of all contour lines being restricted to a single color.

Research direction

Start by locating the contour chart rendering and color-handling entry points in the plotly.js source. Trace how contour lines currently receive their color, then verify that a user-defined array can assign different colors to the lines and that existing single-color behavior remains intact.
