6D strange color tone
Lasers are very specific to a single wavelength, which may not well align with the R, G, B filters in the bayer mask. As others said, try the neutral/faithful picture style to minimize it. You may adjust to a custom WB and it may have an effect on the final color as collapsed to 8bit/JPEG/Video.
If you are a Magic Lantern user, you may try raw video, which gives more data to color-adjust in your video editing program, similar to how raw is collapsed to jpeg in DPP.
