핵심 아키텍처 및 수학 공식
HEX = Concat( DecToHex(R), DecToHex(G), DecToHex(B) )
A standard Hex code (e.g., #FF5733) is simply three 8-bit integers (0 to 255) converted into base 16 format, representing the Red, Green, and Blue light channels.
모범 사례 및 필수 지침
- Understand HSL for UI Design: While Hex is the web standard, Hue Saturation Lightness (HSL) is vastly superior for developers. Changing `hsl(200, 50%, 50%)` to `hsl(200, 50%, 40%)` instantly creates a perfect darker hover state.
- Avoid Pure Black: In UI design, pure black (`#000000`) on pure white creates severe eye strain due to absolute contrast. Use a dark slate gray (like `#111827`) to soften the visual impact.
- Check Contrast Accessibility: Selecting a beautiful color palette is useless if visually impaired users cannot read the text. Always verify your selected colors against the WCAG 4.5:1 minimum contrast ratio.
자주 묻는 질문 (FAQ)
What does the 4th value in an RGBA code do?
The 'A' stands for Alpha (opacity). It is a float value between 0.0 (completely transparent) and 1.0 (completely solid). Modern CSS also supports 8 digit hex codes where the final two characters represent the alpha channel.
Why do colors look different on my phone vs my monitor?
Monitors possess different hardware color gamuts (sRGB vs Display P3) and brightness calibrations. A hex code is a mathematical instruction, but the physical screen hardware ultimately decides how that instruction is illuminated.
What is a Triadic color harmony?
A triadic harmony selects three colors that are evenly spaced (120 degrees apart) on the standard color wheel, providing a highly vibrant, balanced contrast often used in branding.
