Colors 星B-V颜色指数至视RGB颜色
我正在尝试将星星的颜色转换为明显的RGB颜色。除了查找表和颜色渐变外，似乎还没有众所周知的算法来实现这一点 什么是B-V颜色指数？ 这是天文学家分配给恒星的一个数字，用来表示恒星的表观颜色。热星（低B-V）为蓝色/紫色，冷星（高B-V）为红色，中间为白色/橙色 初始算法 B-V至开尔文 开尔文到xyY 如果将恒星建模为黑体，则可以使用的数值近似来计算xy坐标（CIE色度） 问题: 我用B-V颜色索引运行了这个算法：1.2，1.0，0.59，0.0，-0.29。这是我得到的输出 为什么我会得到这种奇怪的输出？热星是蓝色的，而冷星是棕色的，似乎没有白色/橙色的中间星 更新 根据作者的评论，我似乎使用了错误的矩阵将XYZ转换为RGB。因为sRGB是web上的默认颜色空间（或者是吗？），所以我现在使用正确的矩阵，后跟伽马校正函数（Colors 星B-V颜色指数至视RGB颜色,colors,dart,rgb,astronomy,Colors,Dart,Rgb,Astronomy,我正在尝试将星星的颜色转换为明显的RGB颜色。除了查找表和颜色渐变外，似乎还没有众所周知的算法来实现这一点 什么是B-V颜色指数？ 这是天文学家分配给恒星的一个数字，用来表示恒星的表观颜色。热星（低B-V）为蓝色/紫色，冷星（高B-V）为红色，中间为白色/橙色 初始算法 B-V至开尔文 开尔文到xyY 如果将恒星建模为黑体，则可以使用的数值近似来计算xy坐标（CIE色度） 问题: 我用B-V颜色索引运行了这个算法：1.2，1.0，0.59，0.0，-0.29。这是我得到的输出 为什么

在回答为什么没有紫罗兰的问题时：我认为答案是星星不是那种颜色。或者更确切地说，当我们拍摄它们的时候，它们没有呈现出那种颜色。在不同温度/B-V值的情况下，在这条线上产生的颜色对我来说似乎非常准确。拍下我在天鹅座拍摄的Albireo的这张照片：
阿尔比里奥A（左）是一颗B-V为1.074的K型恒星，阿尔比里奥B（右）是一颗B-V为-0.06的B型恒星。看看上面图表中的颜色，这些B-V值与图片有很强的相关性。
另外，别忘了，即使对于非常热的恒星，也会有一些波长较长的输出，这会降低“蓝色”的饱和度。黑体辐射是广谱的。作为对@paddyg代码的修正，它对我不起作用（特别是对于bv<0.4的颜色）下面是Python中的@ SpktRE的C++代码的完全相同的版本：
