Colorado artist Axel Geittmann considers the renewed popularity of coloring books as a great creative outlet. “It starts when we are children, coloring inside and outside the lines. When we get into coloring as adults, it reminds us of that time in our lives,” said Geittmann, who is founder of a marketing agency and started doing public murals and art as an extracurricular activity. Geittmann was chosen to illustrate The Denver Post’s Thanksgiving coloring page, where he introduced elements of Colorado flora and fauna to create an engaging experience.
