FAQ
Example:

- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.
- If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.

Informations about the package colormodel-php
colormodel-php
Convert, manipulate, and generate color schemes across all major color spaces — with a clean, chainable PHP API.
What it does
- 10 color models — HEX, RGB, RGBA, HSB, HSV, HSL, CMYK, CMYKInt, CIELab, CIELCh, XYZ
- Fluent conversions — chain from one color space to another in a single expression
- Color manipulation — rotate hue, mix colors with custom weights
- Color schemes — Complementary, Triadic, Tetradic, Square, Analogous, Tint, Tone, Shade
- Flexible input/output — accept strings, arrays, integers, or named colors like
'red'
Examples
1. Cross-Format Conversion Chain
Start with a HEX color, rotate its hue by 180°, and export as CMYK — perfect for generating print-ready complementary colors from web values:
2. Mixing Colors with Custom Weight
Blend two colors in any ratio. Great for generating palette gradients or brand color variations programmatically:
3. Generate a Full Color Scheme
Feed in any color, get back a complete set of harmonious variations — all returned in the same color model you started with:

Quality checks
You can also run the checks individually:
Backward compatibility policy
- Existing public APIs are kept backward-compatible.
- Legacy usage with
new HEX(...)remains supported. - New APIs are added in an additive way to avoid breaking existing integrations.
