问题描述
如何使一系列RGB颜色在光谱颜色范围内均匀分布？
How would you go about making a range of RGB colours evenly spaced over the spectral colour range? So as to look like a real rainbow.
推荐答案
使用HSL：修正亮度和饱和度，并将色调从0变为360，然后转换为RGB。
Use HSL instead: fix the brightness and saturation and vary the hue from 0 to 360, then convert to RGB.
HSL描述了人们感觉到的颜色。 RGB描述它们，因为它们被机器使用。所以你不能真正做任何视觉上直观使用RGB。
HSL describes colors as they are perceived by people. RGB describes them as they are used by machines. So you can't really do anything visually pleasing directly using RGB.
