With some caveats, to me, the answers are:

1. Definitely Magenta
2. I’d say Cyan, even though it still “feels” to me like “the in-between” of Green and Blue
3. Magenta again, which highly looks like red
4. It’s a draw between Cyan and Yellow, both seem bright enough to be the closest to white
5. Definitely Magenta again, it feels pretty dark to me (and dark, to me, has a good connotation as I’ll explain below).

The caveats are:
- Both laptop and external monitor have IPS panels. If I were to use OLED, quantum-dot displays, Plasma or even the old CRT displays, it’d probably yield different perceptions. I don’t own any of these display types to test this, though.
- The specific shape of Venn diagrams also influences on how colors are perceived: a circle have a smaller area (pi×r×r) than a square (s²) or an equilateral rhombus (also s²). Note: I’m considering s = 2r a.k.a. the side of a square equal to the diameter of a circle. The area, in turn, influences how vision perceives contrast.
- Magenta has no real wavelength so it’s produced solely by the brain when both L and S cones are simultaneously stimulated at the highest intensities by artificial lights (LED).
- I’m currently in a room lit both by daylight and by “cold white” LED lamp. The sky is clear and there’s plenty of vegetation in my vicinity tinting the daylight.
- I access Lemmy using dark mode, and the background is the main aspect influencing contrast (the relationship between colors) and, by extension, perception. Dark background leads to “brighter” colors.
- I use high prescription glasses, and my lenses are slightly yellowed. This possibly influence my perception of colors.
- I have a personal bias towards red and purple due to my specific views on spirituality. Specifically, the way Lilith pulled me in the recent years made me perceive red in a more vivid manner and be attracted to it, while my syntony with Lucifer makes me feel something “divine” with purple (while also sharing some energy with the Lilithian red). Turns out that purple isn’t so perceptually different from magenta, and our RGB displays produce both colors artificially with the similar Red-Blue dance (with magenta specifically having less of blue, therefore being less of a Luciferian color and more of a Lilithian color).
- I’m a former developer and someone who’s worked extensively from UX/UI to graphic design. I built several full-stack webpages, Delphi 7 and VB6 native applications, as well as brands, logos and leaflets. This made me highly familiar with RGB palettes, and this may be another personal bias in my perception.

So, indeed, color perception is highly subjective although living beings share some commonalities when interpreting colors (e.g. red as “danger”; it’s the Carl Jung’s “collective unconscious”).
