生成光谱调色板 [英] Generating spectrum color palettes

问题描述

有一种简单的方法在Java（RGB，HSV和Lab）中的颜色模型之间进行转换。

Is there an easy way to convert between color models in Java (RGB, HSV and Lab).

假设RGB颜色模型：

• 如何计算黑体光谱颜色调色板？

> 修改：我发现 ColorSpace 类可用于RGB / CIE和许多其他颜色模型之间的转换。

I found that the ColorSpace class can be used for conversions between RGB/CIE and many other color models.

推荐答案

也许我不理解你的问题，但你不能真正从RGB输出设备生成一个真正的黑体光谱。有限的色域将是一个问题，如果没有别的。

Maybe I'm not understanding your question, but you can't really generate a true black-body spectrum from an RGB output device. Limited color gamut would be an issue, if nothing else. If all you want is something that visually resembles a black-body spectrum, that's probably a lot easier.

作为近似值，从（R，G，B）斜线0,0,0）到（255,0,0），然后到（255,255,0），然后到（255,255,255）。

As an approximation, ramp from (R,G,B) (0,0,0) to (255,0,0), then to (255,255,0), then to (255,255,255). That'd give you the dull-red to orange, to yellow, to white transition.

如果你想要更科学的，维基百科的文章黑体辐射有一些颜色与温度的关系图。一旦你找出了CIE坐标，你可以将它们转换为RGB在你最喜欢的颜色空间。

If you want something more scientific, the Wikipedia article on black body radiation has some plots of color vs temperature. Once you figure out the CIE coordinates, you can translate those to RGB in your favorite color space.
