Warm, not alarm-red
Red on this site starts as terracotta and burnt orange — heat, not a fire-alarm tile. A flat #FF0000 lock screen is ugly and loud in a bedroom. The scraped orange stroke and the warm tan-orange slab are the two files. The bougainvillea is pink, so it lives on Pink, not here.
If you needed a solid factory red, we have not published it. We would rather you use the painterly warm field than a hex that looks like an error state.
Glare and rooms
Warm reds wash out in hard sun. Indoors they look like a lamp. If you commute on bright sidewalks, tan or navy will hold a thumbnail better. If you sit under a warm bulb at night, terracotta looks like the page.
Pair terracotta lock with tan home. Pair magenta bloom lock with cream or sakura home. Do not pair alarm-adjacent orange with mint unless you like a complementary clash on purpose.
Icons on red
Red fields eat red notification badges. They also fight red app icons. If your dock is already a row of warm icons, pick a cooler home screen and keep red on the lock screen. That is a practical reason we treat these as subjects and accents more than as all-day fields.
Heat as a lock-screen spice
I do not run terracotta under a full work grid. Badges vanish. Warm icons vanish. The lock screen can take the heat; the filing cabinet cannot. That is the whole red page in one commute.
The bougainvillea is floral heat, but it is pink. It lives on Pink. This page keeps the orange stroke and the warm slab.
A future flat red will only ship if it has grain. An error-state hex is not a wallpaper. We will not publish one to capture a keyword.
