Lighter Periwinkle
#A2B3FB
4 parts Titanium White to 1 part Ultramarine Blue. Chromilla's model predicts a 93% dry match against the target, scored against its own color model, not a measured paint-out.
To mix periwinkle (#8A9AE0) in oil, use 2 parts Titanium White to 1 part Ultramarine Blue. Chromilla's model predicts a 96% dry match against the target, scored against its own color model, not a measured paint-out. Chromilla is a web-based paint color mixer that turns any color, from a photo, the camera or a hex code, into exact paint-tube ratios for acrylic, oil and watercolor, using Kubelka-Munk pigment mixing and aiming at the color after it dries.

A soft blue-violet periwinkle. This guide gives you the pigment ratios that land on #8A9AE0 in oil, using the same solver that powers the Chromilla mixer.
Checked August 2026
Ratios calibrated for oil. Start with the dominant pigment, add the modifiers in the order below, and adjust in 5% steps to your target swatch.
1. Titanium White
PW6
2. Ultramarine Blue
PB29
Titanium White and Ultramarine Blue, in roughly a 66:34 ratio.
Start with Titanium White at about 66% as your oil base, then work in Ultramarine Blue in the order above. Adjust in 5% steps until the swatch reads #8A9AE0.
Mixing Periwinkle yourself lets you approximate an expensive or hard to find tube from pigments you already own, match Periwinkle across paint brands whose factory tubes differ, and rebuild the exact color when you run out mid painting. The recipe above is the working starting point.
White cools and chalks a mix as you add it, so tint in small steps and stop before it goes pastel.
Each variation is its own target (lighter and darker move OKLCH lightness by 0.08; warmer and cooler turn the hue 12 degrees toward red or blue), solved fresh.

Open the live mixer with Periwinkle + oil pre-loaded and calibrate to your tubes.
Pigment mixing is subtractive, so small ratio changes matter. The mixer refines this recipe to your brand and updates on the fly.
