yes but, i bet all color blind can see it. **THIS IS A JOKE MEME AND NOT USING MEDICALLY PROVEN** shades of pure red/green with correct luma I could tell that color blind people might still be able to see it. I did not reverse filter out red and green in photoshop, but I have my suspicions Its complex to verify using tools because you need to keep all blue, turn red and green both into green and use proper luma percent based on cone frequencies of eye, then merge back the final green back mixed with blue and save file. Luma percents for human retina per pixel adjust ; ((0.299*R + 0.587*G) + B) [ignores discrete rods effect] : https://www.w3.org/TR/AERT/#color-contrast also humans have 6 different genes for red cones, and that equation is centerline ave red luma in average human many of these colorblind tests mix in BLACK ink, to avoid issues with fading colors (red ink) being discernible earlier, than without shades of grey added.
