Higher CPI = Better for Currency?

On 17th of May - the Uk released CPI data. CPI and RPI at 9:30 but what i dont get it:

CPI came higher than expected but is shown as green (good) on this calendar. Why is that? I thought higher prices is bad for the economy.

Same with RPI, it came lower than expected but is marked as red.

If the data released shows its lower than expected but higher than 0% isnt this good?

Higher CPI leads to higher inflation, Central Banks fight inflation through raising interest rates to make the cost of borrowing money expensive, higher interest rate on one currency makes it stronger against other currencies. So it is GREEN for the currency.

The same goes for RPI with slightly different category, when less than previous, expectations for inflation drop which is bad for the currency.
