Boil the water with the sugar and pandan leaf until the sugar dissolves; cool, and remove the leaf.
In a bowl, mix the rice flour, starches and salt, then gradually add the coconut milk and sugar syrup, mixing smooth. Strain through a sieve.
Divide the batter into two equal parts; colour one pink with a few drops of food colouring, leave the other white (or colour it green with pandan flavouring).
Place a 20×20 cm oiled tin in a steamer, and preheat for 5 minutes.
Pour in about 100 ml of the white batter, and steam covered for 5 minutes, until it sets. Then pour in 100 ml of the pink, and steam that for another 5 minutes too. Keep alternating layers this way until the batter runs out; wrap the lid in a kitchen towel so it doesn't drip.
After the last layer, steam for a further 15-20 minutes, to cook the whole thing through.
Cool completely (at least 4 hours), then cut into diamonds with an oiled knife.

Tips
Cut only once completely cold, as it sticks while warm.
Keeps 1-2 days at room temperature; it hardens in the fridge.
