You can change the colours right? I mean for instance the lower value we can make it blue to show the water and the higher we can make it green?

[@vikasghadamode]

Yes we change colour

what if the only available data is a composite band/layer stack, how do you access each band needed in the calculation of ndvi? i am using planet data and no idea how to extract the bands and put them in the raster calculator
