paint

:art: formerly known as color

Production

@import "node_modules/@plangrid/paint/main";

• main.css is the production bundle
• live.css is the same bundle but with live CSS vars
• module.css shows the module content for both

Low-level atomic API

Stateful atomic classes are made via templates and provided for all swatches for use like class="ccc-blue-500" where the states are described in the legend below. States cascade as shown. Disabled has the highest precedence. State precedence has priority over color precendence. Hover overrides focus...and so on...regardless of color.

• .ccc-* color
  • .fcc-* :focus
  • .hcc-* :hover
  • .acc-* :active
  • .dcc-* :any(:disabled, [aria-disabled=true])
• .ggg-* background
  • .fgg-* :focus
  • .hgg-* :hover
  • .agg-* :active
  • .dgg-* :any(:disabled, [aria-disabled=true])
• .bbb-* border-color
  • .fbb-* :focus
  • .hbb-* :hover
  • .abb-* :active
  • .dbb-* :any(:disabled, [aria-disabled=true])

An earlier simpler less-capable atomic set exists in atomic.css but we plan to move away from those and instead to the ones above wrapped in a higher-level API via JavaScript. See #sheen

Tone

• .tone-validate is designed for inputs using native [aria-invalid] (Recommended)
• .tone-validity is designed for inputs using native constraint validation
• .tone-valid is designed for forcing valid appearance
• .tone-invalid is designed for forcing invalid appearance
• .tone-primary is designed for primary actions (Save)
• .tone-additive is designed for additive actions (Create)
• .tone-destructive is designed for destructive actions (Delete)
• .tone-pill combines primary and destructive for deletable pills
• .tone-secondary is designed for secondary actions (Cancel)
• .tone-icon is designed for buttons represented by icons
• .tone-link is designed for links or buttons appearing as links
• .tone-check is designed for radios and checkboxes

Shadow

Floor-based shadow system

Naming for shadows is based on building floors and elevators. Higher numbers have greater size and greater precedence. See #shadows demo. Open shadow.css to see all available classes

• f floor shadows are raised
  • f30
  • f20
  • f10
• b basement shadows are inset
  • b10
• g ground shadows are glow rings
  • g10

Deprecated shadow classes

• .shadow-raised base static raised shadow
• .shadow-ring applies our standard ring on :focus
• .shadow-halo experimental static raised ring

Blending

Blending patterns are useful for routing colors in component designs. Blending classes themselves are for demoing the technique and are excluded from the main bundle.

| Classes | color | background | border-color | |:--------|:--------|:-------------|:---------------| | .blend .blend-before .blend-after | inherit | transparent | transparent | | .dodge .dodge-before .dodge-after | transparent | transparent | inherit | | .burn .burn-before .burn-after | inherit | transparent | currentColor | | .coat .coat-before .coat-after | inherit | inherit | inherit | | .blot .blot-before .blot-after | inherit | currentColor | currentColor |

JavaScript API

paint

const paint = require("@plangrid/paint")

paint includes a superset of sheen swatch ink. These modules are also each available for direct import.

paint.vivid("blue") // atomic classes for vivid blue paint
paint.glaze("blue") // atomic classes for glaze blue paint
paint.matte("blue") // atomic classes for matte blue paint
paint.swatch("blue-500") // "#0085de"
paint.identify("#0085de") // "blue-500"
paint.nearest("#0085dd") // "blue-500"
paint.ideal("blue-base") // "blue-500"
paint.dyes() // ["red", "orange", ...]
/*...*/

paint classes are also available via the cader interface

paint.bond("VividRed") // paint.vivid("red")
paint.bond("VividBlue") // paint.vivid("blue")

sheen

const sheen = require("@plangrid/paint/sheen")

sheen.vivid("blue") // atomic classes for vivid blue paint
sheen.glaze("blue") // atomic classes for glaze blue paint
sheen.matte("blue") // atomic classes for matte blue paint

// Like above but for states: checked | expanded | mixed | pressed | selected | ...
sheen.vivix("blue")
sheen.glaxe("blue")
sheen.maxxe("blue")

ink

const ink = require("@plangrid/paint/ink")

• ink is special paint for annotations
• dye is the color used to make an ink
• pen types are dry wet gel
• strings are always returned lowercase
• errors console.warn and return ""

ink.wet(dye)

wet ink is available in any dye. Alias ink.user(dye)

ink.wet("orange") // "#f38109"
ink.user("orange") // "#f38109"

ink.dry(dye)

dry ink is available in any dye. Alias ink.master(dye)

ink.dry("orange") // "#e6400a"
ink.master("orange") // "#e6400a"

ink.gel(dye)

gel ink is only available in "blue"

ink.gel("blue") // "#0000ff"

ink.dye(hex)

hex is case-insensitive, pen-agnostic, longhand

ink.dye("#e6400a") // "orange"
ink.dye("#E6400A") // "orange"
ink.dye(ink.dry("cyan")) // "cyan"
ink.dye(ink.wet("cyan")) // "cyan"
ink.dye("#000000") // "black"
ink.dye("#000") // ""

className={`wet-${ink.dye("#e6400a")}`}

ink.dyes(start=0, end=undefined)

Slice an array copy of available dyes

ink.dyes() // ["red", "orange", ...]

ink.dyes is temporarily aliased as ink.inks for crossover support. Please update to ink.dyes =)

swatch

const swatch = require("@plangrid/paint/swatch")

swatch(name) is a custom JavaScript function for providing color by its name in our design system.

swatch("black") // "#1f313d"
swatch("blue-500") // "#0085de"

swatch also works with identical interface in postcss via postcss-functions and node-sass via --functions

box-shadow: 1em 1em swatch("black");
box-shadow: 1em 1em swatch("shade-50");

swatch.identify(value)

• value can be any valid color format
• Returns id of exact match or else throws error

swatch.identify("#1f313d") // "black"
swatch.identify("rgba(31, 49, 61, 0.5)") // "dark-50"

swatch.ideal(id)

• Return ideal id for id
• id may be an alias but the return won't be

swatch.ideal("blue-base") // "blue-500"
swatch.ideal("blue-dim") // "blue-700"

swatch.ideals()

• Return array of all ideals

swatch.ideals() // ["blue-100", "blue-200" ,...]

swatch.nearest(value)

• value can be any valid color format
• Returns id for nearest non-transparent match

swatch.nearest("#444") // "steel"
swatch.nearest("rgb(1, 1, 1)") // "black"
swatch.nearest("rgba(1, 1, 1, .1)") // "black"

swatch.pluck(key)

• Pluck key from registry objects
• Return array of plucked values

Development

git clone [email protected]:plangrid/color.git
cd color
npm install
npm test
npm start
open index.html

Right now the source of truth for the values is in swatch.js and dev.js. Running npm start updates the other files.
