文献在描述蘑菇的颜色时一般使用《Methuen Handbook of Colour》中的色卡，其编号由数字+字母+数字组成。例如：

Pileus light yellow-brown (1B5) or deep yellow (4B5) when young covered with white (2A1) to cream (3A2), powdery or scaly veil, then become (sub)white (2A2,3A2) at the margin and light yellow-brown (1B5) at the centre, finally become grey-white (1B1) at age.

其中的1B5、4B5等都是Methune色卡。这是一个将Methuen色卡转化为RGB的工具。
