当colour意思为“颜料”的时候，属于可数名词，复数为colours当colour意思为“颜色”的时候，属于不可数名词，没有复数。

例如：

As autumn approached， the plants and colours in the garden changed.秋天临近，花园中的草木和颜色也发生了变化。

Pinks and beiges were chosen to echo the colours of the ceiling.选用了粉红色和米色，以跟从天花板的颜色。

At least you have removed your blinkers and can now see the relationship in its true colours.至少你现在已经摘下了有色眼镜，能够看清这段关系了。
