Pixel Art Maker

In this exercise, you'll create your own pixel art maker which allows a user choose colors from a palette and then "paint" pixel art. The interface is completely up to you, but it could look something like this.

More specifically, your pixel art maker should allow a user to do the following.

1. Start with a blank canvas of "pixels".
2. Select a color from a palette.
3. Paint the pixels on the canvas using the selected color.

Here's a development workflow that we recommend you use.

1. Create a small, 2x2 grid canvas made up of white, square div tags with a border.
2. Add an event listener to each div so when clicked the background turns red.
3. Create a small palette of two colors (e.g. red and blue) below the canvas using more div tags.
4. Add an event listener to these div tags so when clicked the current "brush" color is remembered.
5. Expand the dimensions of the pixel canvas.
6. Expand the palette with the rest of the standard colors as well as an eraser. (i.e. red, orange, yellow, green, blue, purple, black, brown, white, etc.)

Bonus Challenges:

• Color Palette: check out http://www.colors.commutercreative.com/grid/ for a list of all standard CSS colors
• Pencil tool: Add the ability to click and drag to draw pencil lines
• Selection tool: Add a tool which allows the user to drag across the screen and paint all pixels that fall inside the rectangular selection
• Add a color picker which allows the user to select any color. Look into HTML5 color inputs
