// If we inherit from base layer, we will add a bit of it
// We add variance of current visible level and the base color 0 or mean (to retrieve initial color) depends on influence
// (baseColor - meanColor) + lerp(meanColor, baseColor0, inheritBaseColor) simplify to
return saturate(influenceFactor * (baseColor0 - meanColor) + baseColor);
// saturate(influenceFactor * (baseColor0 - meanColor) + baseColor);
// There is a special case when baseColor < meanColor to avoid getting negative values.
float3 factor = baseColor > meanColor ? (baseColor0 - meanColor) : (baseColor0 * baseColor / meanColor - baseColor);
return influenceFactor * factor + baseColor;
