Help

The same help you get inside the app, on one page.

Catalog

Every one of the 216 RAL Classic shades, each on its own card showing the shade, its RAL code and its name. Type a code (3020) or a name; diacritics do not matter. The chips filter by the first digit of the RAL code — yellows start with 1, oranges with 2, and so on to whites and blacks with 9. All removes the filter.

Sorting

RAL code sorts numerically, in the order of the printed fan deck. Lightness sorts from the lightest shade to the darkest. Hue builds a chain where each tile is the closest match to the previous one.

Opening a shade

Tap a card and the shade fills the whole screen. Swipe left and right to move between shades; tap once to hide the controls.

Reading the values

HEX and RGB describe the same colour two ways; tap either one to copy it. LRV is light reflectance, from 0 for black to 100 for white — it tells you how much light a surface gives back, which matters for rooms and for heat. Three shades have no official LRV, so the app shows none rather than inventing one.

Favourites

Open any shade and tap the heart in the top right; tap it again to remove it. Favourites are kept on the device and shown by the home screen widget. The free version keeps three.

Settings

The first row shows what you have now: Free, Trial, or PREMIUM. Trial is not PREMIUM. The language can be changed in the app and applies at once — colour names change with it, because they are translated too rather than left in English.
