#no-indistinguishable-colors

Disallow colors that are suspiciously close to being identical.

禁用相似的颜色。

a { color: black; background: #010101; }
/**        ↑                  ↑
 *         Colors like these two */

This rule uses css-colorguard, which itself uses the CIEDE2000 algorithm behind-the-scenes, to determine when colors are so close that they probably should be the same.

该规则使用 css-colorguard，其本身使用CIEDE2000 算法，来决定什么时候颜色是相似的，以至于它们应该是相同的。

In CSS, nearly identical colors often occur because that color was guessed at or eye-dropped at different times, by different people, with different software, etc.; and the intent was always to use the same color, but unfortunately things didn't turn out that way. Instead of having 5 shades of pale light blue, for example, you probably wanted just one,

在 CSS 中，经常出现几乎相似的颜色，因为颜色在不同的时间，不同的人，使用不同的软件等，或猜测或目测，而意图是想使用相同的颜色，但事与愿违。例如，你可能只想使用 1 个苍白的淡蓝色的阴影，而不是 5 个。

#threshold: number

Number can be between 0 and 100. The default is 3.

数值可以在 0 和 100 之间。默认为 3。

The lower the threshold, the more similar colors have to be to trigger a warning. The higher the threshold, the more warnings you will get.

阈值越低就越精确，越相似的颜色必会触发警告。阈值越高精确度越低，你将收到越多的警告。
