If E =$5$ and HOTEL = $12$ , how will you code LAMB?

Direction: If $\text{'}\mathrm{air}\text{'}$ is called $\text{'}\mathrm{green}\text{'}, \text{'}\mathrm{green}\text{'}$ is called $\text{'}\mathrm{blue}\text{'},\text{'}\mathrm{blue}\text{'}$is called $\text{'}\mathrm{sky}\text{'}, \text{'}\mathrm{sky}\text{'}$ is called $\text{'}\mathrm{yellow}\text{'}, \text{'}\mathrm{yellow}\text{'}$ is called $\text{'}\mathrm{water}\text{'}$ and $\text{'}\mathrm{water}\text{'}$ is called $\text{'}\mathrm{pink}\text{'}$, then what is the colour of the clear sky?
