    What I think is funny is that if you assumed E=mc^2 for all particles, then that would mean that red light is lighter than blue light.

      This, too: if E = hc/λ and E = mc², then we can combine both as hc/λ = mc². Rearranging this shit you get m = h/λc. Since h/c = 2.2*10⁻⁴²kg*m, you’d get:

      Photon colour wavelength (in nm) “Weight” (in 10⁻³⁶kg = 10⁻³qg)
      red 650 3.4
      yellow 600 3.7
      green 550 4.0
      blue 450 4.9
