how to color squares created between lines? here is a picture of my problem

Answer 1

Draw your grid flat and create a pattern.

• Create a rectangle
• Choose Object > Path > Split Into Grid... To define the number of sections.
• Fill your sections with whatever colors you want
• Select the entire grid and drag it to the Swatch Panel to create a pattern.
• Draw another rectangle which will be your wall (just draw a straight rectangle)
• Fill the new rectangle with your new pattern
• Choose Object > Envelope Distort > Make with Mesh
• Enter 1 row and 1 column for the mesh and hit OK.
• Select the Free Transform Tool
• Click a corner handle THEN hold down the Command/Ctrl+Option/Alt+Shift keys and drag to create the perspective appearance.
• Move your new pattern filled wall into place.

Adding the Envelope mesh allows the pattern to distort along with the encompassing rectangle. Without the envelope you'll get a distorted rectangle but the pattern within will still be square and flat.

Note: You could also use the perspective grid rather than the Free Transform Tool.

You can also convert your lines into a LivePaint object and use the LivePaint fill tool to color them.
