THE DISCREPANCY // 205
Choose the colour before opening an old photograph. For some people, childhood daylight belongs to a softer yellow Sun; the present seems to hold a harsher white one. Reports describe the difference as a change in the sky they knew. NASA’s spectrum reference describes white-appearing solar light. The file begins where an ordinary summer memory meets that unfamiliar description.
RECOVER THE WHOLE SUMMER
Was it morning or afternoon? A playground, a beach, a window in a particular house? Draw the scene from memory, with its shadows and colours, before inspecting a photograph. This investigation follows remembered daylight and recorded images. A yellow crayon sun and a photographic white disc are different objects to keep in the trail.
A DATED DESCRIPTION OF WHITE LIGHT
NASA’s Astronomy Picture of the Day entry for 27 June 2010 presents a solar spectrum and calls the Sun white-appearing. It gives the reference a date you can return to. Yellow and orange appearances also belong to ordinary sky conditions; a photograph keeps its time, atmosphere, exposure and processing. Which part of your memory feels different: the disc, the landscape’s light, or the whole mood of the day?
THE LIGHT IN THE FAMILY ALBUM
Imagine recognising every person in an old holiday photograph while the light around them seems to belong to today. Would the image settle your colour memory or make the summer behind it harder to reach? The scene may preserve where you stood without preserving quite how being there felt. The yellow in this file could be waiting in that distance.

NASA APOD — All the Colors of the Sun, 27 June 2010 ↗
Primary scientific reference describes white-appearing solar light and its spectrum. A spectrum is not a claim that every terrestrial view or photograph looks white.
NASA — What Color Is the Sun? ↗
Educational reference for the colour question. Atmospheric appearance, image processing and scientific false-colour imagery require their own context.
Reported yellow childhood Sun ↗
Documents the yellow-versus-white memory. No measured historical change in solar colour is established by a recollection.
