# fz_shdr_cbak_colr_avg

Description

Color shader average color function (Optional). This function is called by formZ at certain intervals, to determine an average color for this color shader.
A typical implementation of this function would take all the individual colors used in the shader and calculate the mathematical average; for example : (col1 + col2 + col3) / 3.0.
if this function is not supplied, the average color for a shader is always set to 50% gray (rgb = 0.5,0.5,0.5).
