三基色三通道RGB色域咨询及黄、绿、蓝、紫等颜色色域查询

Hey there! Let's break down the typical RGB gamut ranges for those other colors you mentioned—keep in mind these are common reference ranges used in design, photography, and digital media, since exact gamuts can vary depending on the context (like sRGB vs. Adobe RGB):

• Yellow
  Yellow is a mix of red and green channels, so its blue channel stays low. A typical range is:

  • Minimum: rgb(220, 210, 0)
  • Maximum: rgb(255, 255, 102)

• Green
  Green centers on the green channel, with varying levels of red and blue depending on the shade (bright green vs. deep forest green). A common range is:

  • Minimum: rgb(0, 100, 0)
  • Maximum: rgb(0, 255, 127)

• Blue
  Blue relies on the blue channel, with low red and green values. Typical ranges cover everything from bright sky blue to deep navy:

  • Minimum: rgb(0, 0, 100)
  • Maximum: rgb(102, 178, 255)

• Purple
  Purple is a mix of red and blue channels, with low green. Ranges span from light lavender to deep violet:

  • Minimum: rgb(102, 0, 102)
  • Maximum: rgb(204, 153, 255)

• Orange
  (Since it's a common complementary color, I'll throw this in too!) Orange is a mix of red and green, with higher red than yellow:

  • Minimum: rgb(204, 102, 0)
  • Maximum: rgb(255, 165, 0)

A quick note: If you're working within a specific color space (like sRGB), these ranges might be slightly adjusted to fit that space's constraints. For example, sRGB has a narrower gamut than Adobe RGB, so some of the brighter extremes might be clipped.
