Choose a narrow exercise
Print the flower in simple mode for wide petal spaces. Ask the group to choose two colors for petals and one for the center. That limitation can focus attention on how colors alternate. In detailed mode, the extra center and stem marks provide more small areas, but a person can leave any area uncolored.
Show three approaches
One page can use a single color family from light to dark. Another can alternate warm and cool petals. A third can fill each petal with a different line texture before adding color. These are prompts, not grading rules. Put the examples on scrap paper first so nobody feels obliged to copy a finished example.
Handle the tools
Set pencils and crayons where every participant can reach them. If using markers or paint, protect the table and test whether the paper buckles or bleeds. A dry medium usually makes the quickest low-mess activity. Let younger children use broad strokes; fine petal details are a choice, not a requirement for a complete page.
Discuss what changed
Place two versions side by side and ask which color or texture makes the center stand out. Describe visible choices rather than judging which is better. If the activity continues, print another flower at the same size and try a new palette. The SVG can be enlarged in compatible software, but check the final printer layout before distributing pages.
Try this next
For a repeatable exercise, label the back of each page with the three chosen colors and the date. At the next session, reuse the same flower outline but change just one color. This creates a clear comparison of a single decision instead of mixing many changes together.
