Why clothes fade in a window
Daylight breaks dye molecules, so the face turned toward the glass goes pale first.
When the purchase is complete, return to the original window. It will refresh.
From the opening
Clothes fade in a window because daylight, especially ultraviolet and the energetic blue end, breaks or rearranges dye molecules. Color is a structure, and when that structure is damaged it no longer absorbs the same light, so the cloth looks paler or shifts hue. The opening covers light breaks the dye molecule, the exposed face goes first, and glass blocks only part of the light.
The rest of the brief — the later sections and the reading notes — opens after Stripe confirms payment.
