Distance of selected colors represented as wavelengths λ (blue, 400 nm; green, 550 nm; red, 750 nm) from the ball center calculated from the diffraction-grating equation (r_calc) and measured from microscopy images (r_meas) as fractions of the ball radius r_ball for all visible diffraction orders (D.O.)
