HEX 转 RGB

HEX is simply a hexadecimal notation for RGB values. Each pair of characters in a HEX code represents the same 0-255 value as in RGB, but in base-16 instead of base-10. For example, #FF0080 translates to RGB(255, 0, 128).

RGB is more readable when you need to understand or manipulate individual color components. It's also required when working with transparency (RGBA). HEX is more compact and commonly used for static color definitions in CSS and design software.

RGB values represent the intensity of red, green, and blue light that combine to create a color. Each value ranges from 0 (no intensity) to 255 (full intensity). When all three are maximum (255), you get white; when all are minimum (0), you get black.

RGBA adds an alpha channel to RGB, representing transparency. The alpha value ranges from 0.0 (fully transparent) to 1.0 (fully opaque). This is useful for creating layered designs where colors need to blend with underlying elements.

由于屏幕校准、显示技术（LCD、OLED 等）和制造工艺的差异，颜色可能会发生变化。虽然十六进制值和 RGB 值精确，但实际显示效果可能会有所不同。对于关键应用，请考虑颜色校准。
