Somethings not working right... >:(

So I saw the Riot Points Art thing and I said hmm i'll try it. So I go to the website and start a drawing. And then every time I click on a color it stays black I can't choose colors!!! Then I click download when i'm done I thought maybe it'll show the colors anyway. Well when I downloaded it it just shows a white screen with my drawing on it and I can't do anything with it. So I tried dragging it on to my laptop and I did then I tried posting it onto here all it does is turn into the stupid white page with my drawing on it then I try copying the www.whateverwhatever thing so I could post it on here but when i try to copy it it goes on forever!!! anybody know how to do this!
