Dammit, red / green colorblind and I’m not able to read it either. I even took off my glasses, which sometimes helps. I can tell there’s something but I can’t make it out.
I'm mildly colorblind and I can figure it out with some effort. I can kinda see a ever slightly variation and can trace it with my finger to figure out the shape of the letters.
There are differing scales of deuteronopia (what red/green color blindness is called). The more overlap between the ranges your red and green cones' wavelength reactivity, the worse the colorblindness. Mine is not super bad, just enough to be annoying sometimes.
It does appear that it's a red/green color blindness thing, but perhaps the camera picked up the colors slightly differently than it would actually appear in person.
So, even though you can manage to read it on your screen, you might actually not be able to make it out in person. 🤷♂️
Please correct my ignorance here - coloured reflections and colourblindness together is interesting!
If this pillow in OP is similar to one I have, even though its a green to black sequin pillow, the green sequins reflect various shades and almost colours, depending on angle and how the light catches it.
Is it possible that if the pillow was completely face on, it would be within your blindness range, but tiled slightly the colour shifts to a range you can see?
Well, first, there is not a range for which I am "blind" to greens/reds, as in I would only see greyscale or something. Rather, there is a range of overlap for which both my green and red cones in my retina react to the light and so I essentially see both green and red, making the colors hard to distinguish. (Fun fact. As a result of this, I actually see slightly more blue that the average person.)
But when it comes to the green sequins, the tone/brightness of the light shouldn't matter. It is the frequency of the light, not its relative intensity (above a certain level), that determines which cones are activated. So if they are all different shades of the same hue, they may fall into that overlap. But if it is partially reflecting other colors of light, then yes, the angle of the sequins may change how I am able to perceive the color(s) depending on those reflections.
