What color uses less energy?

The color that uses the least energy depends on the context: Black is most efficient for OLED screens (using pixels that turn off) and absorbs heat least efficiently in sunlight (needs more cooling), while White/Light Colors are best for buildings as they reflect solar heat, reducing cooling needs, but use more power on OLEDs. For digital screens, darker colors (especially black) are best; for physical surfaces and buildings, lighter colors are best for energy efficiency in heat.

What color uses the least energy?

The color that uses the least energy depends on the context: for physical light (like LEDs), red has lower energy photons than blue/green, while for digital displays (OLED), black (no light) uses virtually no energy, followed by red/green, with blue using significantly more; for paint/building colors, lighter shades reflect heat, saving AC energy, while darker ones absorb heat.

Dark mode isn't universally better; it reduces glare and can help in dim environments by lowering brightness, but in bright conditions, it can strain eyes by dilating pupils and causing fuzziness (halation), making light text harder to focus on, so the best choice depends on your surroundings and visual needs, often requiring personal testing. For most people, light mode (dark text on white) offers better clarity, while dark mode excels at reducing overall light emission in dark rooms, but the key is to combine it with regular breaks (20-20-20 rule) and blink often.
