As you can see a capsule has two main parts and the size of the two parts are different from each other, one is wider than the other and has more content than the shorter one.The one that is shorter is referred to as the ‘cap’ while the wider one is referred to as the ‘container’. The reasons for companies to opt for both of them having different colours is to increase their possibilities of identification, having two different colours in one capsule gives them more colour combinations in order to differentiate medicines.
Having two different colours were implemented for them to increase the production efficiency as there is now an increased number of permutations and combinations that are possible.
Having two different colours in one capsule gives patients and mediacal practitioners more colour combinations to differentiate their medicine and product.
The colour perception of patients is also enhanced as having a colourful pill is more appealing to the eye and will result in increased sales. The colour of capsules or any medicine plays very important role for identification among many other medicinal capsules. Specifically for patients with multiple diseases and illnesses and taking various medicines patients should be able to identify and segregate their medicines based on their colour.
