The three cone fundamentals are the spectral sensitivities of the long- (L-), middle- (M-), and short- (S-) wavelength cones measured relative to light entering the cornea. They are also the fundamental color matching functions (CMFs), which in colorimetric notation are referred to as \( \overline{l}\left(\lambda \right) \)
