Working from a stack of five colours at a time, and swiping between stacks, instead of choosing from all 24 the tin pigments at once.
Where this landed. The card of five and the swipe are what shipped. What changed afterwards is what sits on the cards: not six stacks covering all 24 pigments, but four palettes of a few paints each, with their washes on the card beside them.
Each is the bottom of the phone at true scale. Swipe to change stack, tap a colour to paint with it, and drag along the thin line just above the cards to set the brush width. The circle shows the colour at the width it will paint.
One card of five joined colours at the bottom, with the next and previous stacks peeking in at the edges. Swipe sideways to change stack; tap a colour to paint with it. Each colour is 64pt wide.
The same card, with a small circle on each seam between two colours showing what the pair make together on paper. The circles are real pigment mixes, worked out when the page was built, so they are a guide to which neighbours to put side by side.
Five separate pills instead of one joined card. Taller and easier to hit, and a little more like pans in a tin, at the cost of more height on screen.
The stacks sit on top of each other like a deck of cards, with the edge of the next one showing. Swipe up or down to flip through them, which leaves sideways free for anything else.
Each is five pigments that work together for one kind of subject. Between them they cover all 24, so nothing in the tin is out of reach, only a swipe away.
Six versions of a radial dial rising from a puck, ending in one arc that flowed warm to cold with a thin line for width. The full record is on the colour dial page.
Showing all 24 at once was the wrong goal. A painter lays out a few colours for the subject in hand, not the whole tin.
One stack of five colours at a time, chosen to go together, with a swipe to the next stack. Six stacks cover all 24 pigments. The thin width line with click-stops and the colour circle above both carry over from the dial.
