Oil painting by numbers: ocean wave practice page

Create a 300 DPI A4 portrait printable digital painting exercise page. Use a simple black and white line drawing, inspired by the powerful waves of Japanese Ukiyo-e prints, featuring large, rolling waves, irregular, foamy edges, a small hill on the right horizon, and abstract cloud or sky shapes in the background. Keep the drawing within a thin rectangular border and leave wide white margins. Divide the illustration into clearly defined coloring areas, using smooth black outlines, and center the number label in each area. Use 10 coloring numbers throughout the work, repeating the area labels where appropriate: 1 represents the large wave foam/white area, 2 represents the cream-colored wave crest, 3 represents the sky-blue wave area, 4 represents the slate-grey wave/background area, 5 represents the coral-red small wave area, 6 represents the light gray lower foam area, 7 represents the red lower wave band, 8 represents the dark cyan lower right wave band, 9 represents the parchment-brown wave band, and 10 represents the foam white horizon/sky band. Add a bold title at the bottom below the border artwork.{argument name="headline text" default="illustrate"} The sentence that follows{argument name="instruction text" default="Please fill in the area with the corresponding color."} Below the description is a two-line color chart with 10 numbered square color blocks and labels: 1 Prussian Blue, 2 Cream, 3 Sky Blue, 4 Slate Grey, 5 Coral Red, 6 Light Grey, 7 Red, 8 Dark Cyan, 9 Parchment Brown, 10 Foam White. Make the color blocks small and horizontally aligned on the page, with each colored square labeled in black and accompanied by its color name. The overall style should be simple, clear, and printable; illustrations should have no shadows, no extra decorations, no watermarks, and all text should use a simple sans-serif font.
