Using Colors and Theming

The strings #FF5733 and rgb(255, 87, 51) produce exactly the same color, because React Native converts every color string to one number before it reaches the native side. The function processColor shows that conversion.

#FF5733                  4294924083
rgb(255, 87, 51)         4294924083
rgba(255, 87, 51, 0.7)   3019855667
#FF5733B3                3019855667
notacolor                undefined

The formats are therefore only different ways of writing the same information, and you can choose whichever is easiest to read. You can use a name such as 'red' or `'transparent'
