Question 1

How to lighten a color using the Color library?

Accepted Answer

Use the .lighten(amount) method, where amount is a fraction (e.g., 0.5 for 50% lighter). For example, Color('#ff0000').lighten(0.5) returns a new color instance. This is chainable with other methods like .alpha() for further adjustments.

Question 2

Color vs chroma.js: which is better for advanced color manipulations?

Accepted Answer

Color excels in immutable operations and CSS string support, making it ideal for web projects with predictable state management. Chroma.js might offer more perceptual color spaces and gradients, so choose Color for strict immutability and web standards compliance.

Question 3

How to calculate WCAG contrast ratio between two colors?

Accepted Answer

Use the .contrast(otherColor) method. For instance, Color('white').contrast(Color('black')) returns 21, the maximum ratio. This helps ensure accessibility by checking if text meets WCAG guidelines, with lower ratios indicating poor contrast.

Question 4

Does the Color library support CSS Color Module Level 4 features like lab() or lch()?

Accepted Answer

Yes, it supports LCH and Lab color spaces via .lch() and .lab() methods, as shown in the constructors. This allows modern color manipulations, but note that it might not cover all CSS4 syntax like color() function or new spaces without updates.

Question 5

How to install and use Color in a Node.js project?

Accepted Answer

Install via npm with 'npm install color', then import using 'import Color from "color"' or require(). Construct colors with strings or objects, and chain methods for transformations, as detailed in the usage section of the README.

Question 6

Is the Color library tree-shakeable to reduce bundle size?

Accepted Answer

The README doesn't specify tree-shaking support, and as a CommonJS module, it might be challenging to optimize. If bundle size is critical, consider this limitation or use alternatives with ES modules for better tree-shaking in modern builds.
