Choose a palette
The rainbow page has several broad arcs and cloud shapes. A familiar spectrum is one option, but a two-color or monochrome design can work as well. Ask participants to choose colors before they begin so they can see whether they have enough distinct shades for their plan. Simple mode keeps the spaces broad; detailed mode adds a few small accents.
Share the work
For a group page, assign one arc or one cloud to each person and agree on a rough palette. If people prefer independence, print multiple copies instead. Collaboration is easier when the task has clear boundaries and nobody has to paint over someone else’s work. Put a protective sheet underneath if several markers are being used at once.
Check the print
Choose Letter or A4 to match the loaded paper. The preview shows the outline but cannot know printer margins. Look at the print dialog to confirm the whole rainbow, cloud edges, and title fit. Print a test before making classroom quantities. If the arcs look too small for the intended crayons, enlarge the SVG in a compatible editor and recheck page fit.
Add a message
Use the empty area around the drawing for a short note, a date, or a person’s name. Keep the note away from the title and line art. A completed page can become a card or a temporary display. If photographing group work, obtain permission from the makers or their caregivers as appropriate. The page stands on its own without a specific celebration date.
Try this next
If a group has limited time, color only two arcs and one cloud, then return later. Write the chosen palette on the back so everyone remembers the plan. A partially colored page can still be a useful draft; the point is to leave a clear next step.
