Slab Knife Hue: Paint Mixing

You found the perfect color. Now you have to mix it — and half a tube later, it's still not right. Slab Knife Hue tells you which of your own paints to use, and in what parts. HOW IT WORKS Lift a color from any photo with a loupe, or dial it in by hand. The app tries every pair and trio of tubes you actually own. You get a clear recipe: Titanium White 6, Yellow Ochre 2, Burnt Sienna 1. Mix it, save it to your project, come back to it next week. WHY PAINTERS LOVE IT No more muddy guesswork or wasted paint. No more "how did I mix that sky?" The recipe is written down, with the exact tubes from your own box — acrylic, oil or gouache. SQUEEZE AND STIR Hold a tube to squeeze paint onto the slab, part by part. Then sweep the palette knife in circles and watch the streaks marble together until the final color appears. It feels like the real table, minus the cleanup. WET TODAY, DRY TOMORROW…
