gee, i missed out big time. please someone start that as a special discussion and prove to me how you could add an extra dimension into the Lab colorspace.
i beg you shampa, show me how you could squeeze an extra few nanos into the wavelength between blue and red light. that would be a revelation to all of us i guess and i would be the first to bow before you. 390 to 750 nm was all i ever knew to exist for visible light.
please come back and explain! i beg you. because i am missing the point here.
