This is a coloring game! Click space to change the page. Up and down arrows to hide and show the sliders. The black dot show the opacity, the oval thing is where you test colors. Click the green flag to delete every thing. The sliders do what they say, the little buttons in the corner work the palette. You can save colors on the palette by making your color, and clicking the "add color" button. You can open the palette to look at the hue, saturation, brightness, and opacity of you color, and then match the numbers on the palette to the sliders. The "clear palette" deletes all of the colors on the palette, so do not click it unless you are sure. There is one empty page for you to edit. There is also a page where you can just doodle.
Click V while you are in the empty page for a surprise. Click B to turn it off.
