Imbue
Wide color picker made using SwiftUI & Combine
Model
ColorValue
.RGB struct
Holds red, green, and blue values using the CGFloat type.
.Lab struct
Holds lightness, green-to-red, and blue-to-yellow values using the CGFloat type. These values are designed to map closely to how our eyes responds to light — to “mimic the nonlinear response of the eye”.
.sRGB(RGB) case
The colorspace used by the web, many phones, tablets, and PCs. In other words, it is common-denominator with wide support.
.labD50(Lab) case
The colorspace used by Photoshop and Affinity Photo. Supports wide color (aka HDR).
ViewModel
AdjustableColorInstance
Conforming to SwiftUI’s BindableObject protocol, this holds the source of truth for the app.
It has a .State struct to hold the actual values. This makes notifying the willChange publisher easily, simply by using the willSet property method.
View
SwiftUI components which used ObjectBinding properties to subscribe to the ViewModel.
