Our first tree plays with color in a bright change from traditional red and green. It plays with shade of green, geometric shapes and layers. I think it would be a great card for a little boy.
The last three images are modifications on the same design, playing with color, texture and glow. The first image is traditional red and green, with bursts of yellow poking out between the poinsettias.
The second image is more elegant, a golden tree with red berries poking from the green tree.
And the final image is a fun colored tree just a slight variation of color to bright fuchsia with glowing yellow beads and the standard tree against a snow white backdrop.
