I wondered briefly if it was possible to colour our blue ones a different shade, but decided that being the only people with a wheelchair would probably make us a little conspicuous.

我短暂地想知道是否有可能给我们的蓝色衣服涂上不同的颜色，但我决定作为唯一坐轮椅的人可能会让我们有点显眼。

So you can see the slight variation here and how useful it is to be able to describe colour, shades like this with slightly different variations to have different words to describe it and be more specific.

因此，你可以在此处看到细微的变化，以及能够像这样使用不同的词来更加具体地描述具有略微不同变化的色调是多么有用。
