Which kind of colorblindness? Because I’m red-green colorblind (the most common kind) and I can read it.
My dad is red green color blind. I just showed it to him and he couldn’t read it.
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.
Thank you so much!
A green sequin always reflects a specific frequency but maybe have different tones and intensity - I see this as a “different” colour, but really its green and it would always appear grey to you?
Whereas an iridescent one as a different example which has multiple different colours depending on the angle (red to purple, but that idea), you maybe able to see it reflecting purple but could also appear greyscale?
