I am trying to achieve an understanding on how to create a pattern of the same shape repeatedly by copy and pasting and changing the colours of each of the circles. I did not have any trouble on creating this pattern as I have used Adobe Illustrator before in my previous school. The colours of the pattern is still not good enough. The reason why I choose black is so that the colours of the circle will match. And it wont matter what colours you put on the rest of the circles because it will match.
