如何在JavaScript中生成一个颜色较浅的随机十六进制代码？ [英] How do I generate a random hex code that of a lighter color in javascript?

问题描述

我为背景使用随机颜色，但由于文本是黑色的，因此当生成真正的深色时，文本将无法看到。如何在生成十六进制代码时排除这些暗色？

我只能弄清楚如何得到它：

Math.floor（Math.random（）* 16777215）.toString（16）

不排除黑暗的颜色。有人可以帮我吗？

预先感谢您！

解决方案

我要做的是为每个（RGB）（即 000000 到 FFFFFF ）生成一个从00到FF的数字。 。我也会确保G值大约高于33。

I am using a random color for the background, but since the text is black, when really dark colors are generated, the text can't be seen. How do I exclude these dark colors when generating the hexadecimal code?

I could only figure out how to get this:

Math.floor(Math.random()*16777215).toString(16)

But this does not exclude dark colors. Could someone please help me?

Thank you in advance!

解决方案

What I would do is generate a number from 00 to FF for each (RGB) (ie 000000 to FFFFFF). I would also make sure the G value is approximately higher than 33.
