Kolorist is a colour tool for designers and architects on iPhone, iPad and Mac. Build palettes across colour spaces, turn them into design systems, check contrast and colour vision, see colours in 3D and in the light where they will be used – and get them into the tools you already use.
FROM PALETTE TO DESIGN SYSTEM
• Roles for accent, neutral and status give colours for light and dark mode, with and without increased contrast – your brand colour is kept wherever it meets the requirements
• See the colours on buttons, fields, switches, alerts and tabs, with the contrast for each colour pair
• Tone scales with the same contrast for every hue, right in Studio
• Export as colour sets for app development, design tokens and CSS with light and dark mode – or share the design system as a link
EVERY COLOUR SPACE
• Edit in OKLCH, OKLab, CIE LCH, CIELab, HSB, HSL, RGB and CMYK
• Display P3 side by side with sRGB, Adobe RGB, CMYK or any ICC profile – mapped, never clipped
• Gamut limits on the sliders show where the colour falls outside the colour space
• Enter CMYK or RGB in the profile they will be used in, and get clean CMYK values
COLOURS AND COLOUR SPACES IN 3D
• Harmonies, palettes, gradients and colour libraries in a colour sphere, in OKLab or in CIELab
• Live 3D view of the selected colours next to the tools
• Compare the colour spaces of ICC profiles, with a choice of rendering intent
• Share as a 3D model, and see the colours in your physical surroundings through AR (augmented reality)
COLOUR LIBRARIES, ICC PROFILES AND FILAMENT
• Import your own colour charts in ASE, ACO or ACB with named tones
• Filament colours for 3D printing: more than 2,200 colours from 150 manufacturers, most of them measured – find the nearest filament
• Your own ICC profiles, synced through iCloud
GRADIENTS, TONES AND HARMONIES
• Gradients in equal perceptual steps in OKLab, with lighter and darker rows
• Harmonies from monochromatic and tone path to triad and square, on OKLCH, CIE LCH, Hering, Goethe, HSL or RYB colour wheels
CONTRAST AND COLOUR VISION
• Contrast check by WCAG 2.2, APCA or LRV, with auto-fix that adjusts the colour until it passes
• Text contrast and text colours for palettes
• Contrast between surfaces for buildings and interiors: LRV difference, Weber or Michelson – in the chosen light too
• See palettes with colour vision deficiencies, with confusion lines in a chromaticity diagram – and which colours become hard to tell apart
• Colour reports you can copy, share as a link and print
LIGHT AND COLOUR MEASUREMENT
• See colours and whole palettes in your own and standard viewing conditions
• Measure the light with the camera, and compensate the colours you pick with a grey card or reference card (beta)
APPLE INTELLIGENCE ON DEVICE (EXPERIMENTAL)
• Suggested palettes from value words, grounded in a knowledge base of more than a hundred colour concepts
Everything runs on device. Without Apple Intelligence, the suggestions are built straight from the knowledge base.
SHARE, SAVE AND EXPORT
• Share colours, palettes, gradients and harmonies as links – recipients without the app see them in their browser
• Save as ASE, ACO, design tokens, CSS, SwiftUI, GPL, SVG, hex and PDF
• Copy colours and gradients straight into design, layout and presentation apps – or as RGB values for CAD, BIM and video
• Print palettes and palette groups on A4 in CIELab
PALETTES AND ICLOUD
Collect colours and gradients in palettes and groups, synced through your private iCloud.
OPEN ABOUT METHODS
The app shows the methods it builds on, from OKLab and CIEDE2000 to WCAG and APCA, with source and explanation.
PRIVACY
No account, no analytics, no ads and no tracking. The developer collects no data.
