Correlation residuals of the I‐band relations with ﹩V-I﹩ color. The top panels show the color‐luminosity (left) and color‐rotation velocity (right) relations. The middle panels show the residuals of the VL relation vs. the color residuals at constant L (left) and constant V (right). The bottom panels show the size residuals vs. the color residuals at constant L (left) and constant V (right). The dashed lines give predictions based on scatter in color at fixed stellar mass and assuming, based on stellar population models, that color is related to stellar mass‐to‐light ratio.
