Step 6
I used the Rectangle Tool (M) to draw three simple shapes on the bottom three edges of the original inner hexagon (the dark mustard one). Use the Direct Selection Tool (A) to angle the two shapes on the side so they mimic the angles of the hexagons within the honeycomb shape. Apply a Linear Gradient to each going from R=255 G=189 B=63 to R=255 G=234 B=144 and back again. Reduce the Opacity of each shape in the Transparency panel to 42%.
