+
+Now that almost all computers, and all modern computers,
+have support for 24-bit colour, colour dithering have
+faded to unexistence. The common logic is that the colours
+are good enough, or that we can only perceive 10 million
+colours, and 24-bit colour gives us almost 17 million
+colours. However, we can see the difference between
+two colours if they are next to each other and painted
+on large areas, even if the difference is the smallest
+that 24-bit colour can bring us.
+
+So whilst 24-bit colour is good enough in most cases,
+it is not enough in gradients where the difference
+between the end colours are low, especially when these
+colours are bright. Therefore we still need dithering
+in some cases.
+
+Now that we get increasingly higher pixel pitch our
+display output, dithering is going to look increasingly
+better.
+
+Since we somehow got stuck at 24-bit colour, dithering
+is important.
