Colorlogix - Color Design Tool app for iPhone and iPad

Colorlogix makes it easy to design palettes, adjust, convert, and share colors. Powerful controls let you quickly switch between color models, component formats, and color spaces. Share your colors to images, CSS, Swift, SwiftUI, and more.

Upgrade to Colorlogix Pro to unlock the full feature set including color combinations, sharing to source code, image color picking, and iCloud Sync.

• Edit Colors

Colorlogix handles color model conversions and formats for you. Just one tap converts between RGB, HSB, HSL, or CMYK.

Edit values as integer, hex, percent, decimal, or degrees. A custom hex keyboard makes editing hex values simple.

The interactive color wheel and slider controls react simultaneously as you adjust colors. Choose between Red-Green-Blue or Red-Yellow-Blue color wheels.

• Create Color Combinations (Pro)

Easily create Complementary, Split Complementary, Triad, and Analogous color combinations. Related colors are automatically linked together and updated as you make changes.

Adjust the offset angle of Analogous and Split Complementary color combinations.

• Pick Colors

The Colorlogix image color picker (Pro) provides a precise, zoomable interface for finding colors in images. View both RGB and HSB values as you pan within the image.

A convenient popover color picker lets you quickly pick from a color grid or from lists of common colors. Choose from CSS Colors, iOS System Colors, Grayscale, and more.

• Design and Share Palettes

Create your own library of color palettes with Colorlogix. Synchronization with iCloud (Pro) lets you access palettes on all your devices.

Each palette can be rendered in sRGB or Display P3 color spaces, and you can easily convert between color spaces.

Share your palettes as reference card images, hex, or source code (Pro), including CSS, Swift, and SwiftUI.

• Share to Source Code (Pro)

Colorlogix makes it easy to share your colors to CSS, Swift, SwiftUI, or Objective-C. With syntax-colored source previews you can easily view and adjust the code.

Using Universal Clipboard on iOS or iPadOS makes it easy to copy a color from Colorlogix to your Mac.
