Why molar extinction coifficient of KMNO4 is much higher than that of CoCl2?

Molar extinction coefficient is depend on intensity of the colour of solution.If the solution has high intensity of colour, molar extinction coefficient is high.So when considering CoCl2 and KMnO4, CoCl2 has low colour intensity. KMnO4 solution has much intense purple colour.Therefore its Molar extinction coefficient is high.
