> does not really mean much here [...] impossible to directly observe As misconceptions are common around the Sun, sunlight, and colour, it can be helpful to crosscheck concepts by swapping the Sun for a more familiar object: a light bulb, display, wall, shirt, or elephant. Imagine an article about a newly energy-efficient light bulb, which included only false-color thermal and near IR images - "Look, less waste heat and wasted light!". Would it seem odd to suggest adding a true-color visible-light photo? What if the authors color graded such a photo to hide a less marketable, say greenish cast? Years ago, NASA did a traveling museum exhibit on the Sun with lots of colorful images, but not a single white Sun. Now imagine a traveling exhibit on elephants. With colorful thermal IR images of ears as radiators, and false-color images of skin parasite distribution (thus mud baths) and so on. But not a single grey elephant. How odd would that be? Presented with "A 5-year old asks: The Sun is a big hot ball... what color is the ball?", it's not uncommon for first-tier-U physical-sciences graduate students to answer with variations on "it doesn't have a color; it's lots of different colors; it's rainbow color", reflecting misconceptions around color perception. Which then might be probed with "A 5-year old asks: what color is that shirt?". "Why does the Sun shine? Fusion!" becomes "Why does the LED light bulb shine? Electricity!", highlighting the incompleteness. Another crosscheck is seeing how the non-uniform appearance of the Sun (limb darkening) is handled. With the edge/limb appearing darker and redder because of longer sight lines through cooler higher layers.
