### Playground

- A [color picker](https://invisibledetails.com/playground/color-picker) you can actually use - sRGB and Display P3, an OKLCH-aware hue ramp and every notation CSS Color 4 can print. It is a copy of the one in [Paper](https://paper.design/).

### Improvements

- Preferences now open in a dialog instead of a nested menu - the same panel from the account menu and from the gear on free lessons.
- New Text size setting for Reader mode - the default plus two larger steps. Examples keep their size.

## Jul 25, 2026

### Improvements

- Raised the contrast of secondary text across the app - the lighter greys were failing WCAG AA in light theme. Lesson body copy now sits a step brighter in dark.
- New Reader mode preference: strips a lesson to the text - no contents rail, no card edge, a narrower column.

### Free lessons

- Preferences and theme are now reachable without an account - the gear in the bottom-right corner of any free lesson.

## Jul 24, 2026

### Improvements

- Reading preferences in the account menu now say what they change - one short line under every toggle.

## Jul 22, 2026

### Free lessons

- Three lessons are now open to everyone, no account needed: [Learning to notice](https://invisibledetails.com/preview/learning-to-notice), [Small details that add up](https://invisibledetails.com/preview/small-details-that-add-up) and the [Stepper](https://invisibledetails.com/preview/stepper) breakdown.

## Jul 20, 2026

### Launch

- Invisible Details is live. The course opens with 13 notes on the principles and 6 practice breakdowns of real components - and it will keep growing from here.
