How they made colours

I've just got home from colouring the comic project in my church. And there's one thing that make me amazed and embarrased at the same time. It's that, today was the time we coloured the pics using wall paint. The thing that amazed me was the way they made those colours. They just bought one big bucket of white colour, then mixed it with 3 primary colour: Red, Yellow, and Blue. Then we have 5 colours: White, Red, Yellow, Blue, and Black (I think they bought a small can of black colour).

Now, to have all other colours, they just do mixing!! And there, now we have light blue, dark blue, pink, skin colour, etc. I'm amazed!! And also embarrased, since, well...... I couldn't do nothing to help. I don't understand the mixing thing, and just stood there watching.

But of course, I help them in applying those colours to the pics. And I never know that colouring pics could be that fun!! Time really passed very quickly when doing that ^_^ well.... of course we can't finished in one night. I'm really looking forward to do painting again ^o^
