在化学试剂中，把带有颜色或可改变颜色的一类试剂统称为色素试剂，它包括了指示剂、显色剂和染色剂。

酸碱指示剂是遇到酸、碱能改变试剂颜色的指示剂，主要用来指示溶液的 PH 值，指示酸碱滴定的终点，如：甲基橙、酚酞、甲基红等。这些酸碱指示剂也是一种染料，但一般染料并不能直接作为酸碱指示剂，一般要进行提纯，严格控制试剂中的杂质含量，否则可造成 PH 值变色范围的迁移，影响滴定分析的结果。

氧化还原指示剂是指遇到氧化剂或还原剂能改变颜色的试剂，主要指示溶液中的氧化剂或还原剂的存在、用于指示氧化还原滴定分析的终点，如二苯胺、二苯胺磺酸钠、次甲基蓝、邻二氮非 - 亚铁等。

能指示络合滴定终点的指示剂称为络合指示剂，因络合剂与金属离子之间的反应，所以络合指示剂一般均为金属离子的显色剂，如二甲酚橙、铬黑 T 、 PAN 、 PAR 、酸性铬兰 K 等。

在显色剂中还有很多是门为光度分析用的金属离子显色剂如铜试剂、双硫腙、钒试剂、铝试剂等。这类试剂要求含量较高，欲测的金属离子和有干扰的离子要求含量较低，否则就会造成空白值低，吸光度误差大，测定值不准确等。

色素中还有一种试剂称为生物染色剂，他是用于生物体的染色和结缔组织、细菌草软毛、昆虫活体、细胞壁、细胞核的染色。如次甲基兰、酸性品红、碱性品红、中性红、考马斯亮兰等，这些试剂有的需直接合成，有的可从工业染料中提纯制备。如次甲基兰，染料次甲基兰中含有大量锌盐，必须洗掉锌盐才可作为生物染色剂。

值得一提的是工业染料的名字与染色剂的名字有很大的差异，千万不要混淆。如染色剂的酸性品红和染料的酸性品红的结构式分别为：酸性品红（生物染色剂）  酸性品红（染料）
