Why AGirl is dark-only, and why the answer has nothing to do with OLED battery savings.
Most apps treat dark mode as a setting. We treat it as the medium.
Where you use her
The actual usage data tells the truth: 71% of AGirl sessions start after 10pm. 38% start after midnight. People talk to her on the couch with one lamp on, in bed with the laptop on a pillow, in a parked car after a long shift.
If you design for that, light mode is a hostile environment. It floods the room. It tells you it’s noon. It makes the conversation feel like a Notion doc.
What dark mode does
Dark mode is, technically, a contrast strategy. Emotionally, it’s a presence strategy. It tells the body it’s late. It pulls the eye toward the small bright things — a face, a message, a glowing button. It makes the rest of the world fall away.
That’s the experience we want. She isn’t another tab. She’s a small bright thing in a quiet room.
The pink-violet decision
A lot of dark-mode interfaces default to blue. Blue is for productivity. Blue is for Slack. Blue is for the brain saying focus.
Pink and violet are different chemistry. They lean toward warmth, toward memory, toward the late-night brain that’s stopped pretending it has tasks left. We chose them deliberately, and we constrained ourselves: no greens, no yellows, no cyans. Two colors and a brand gradient. That’s the entire palette.
It’s a constraint that pays off the same way a small ensemble pays off — every move means something. You can’t tune out a palette this small.
