Choose a scope you can finish
For an early exercise, a small still life is easier to manage than a full landscape with trees, water, and distant buildings. The square-cell reference helps divide the image into manageable areas. Fewer colors and larger cells can simplify the task, though they also remove subtle shapes and shading.
Prepare your own painting guide
Numbers group sampled colors, while the cells contain light hints of those colors. This version does not append a palette legend, supply paint-brand codes, or separate the image into organic shapes. Use the original to choose your materials, then write down a manual color guide if you want to work away from the screen.
Test the exported sheet before scaling up
Download the raster PNG and print a small proof. The paint conversion caps the longest edge at 960 pixels, so inspect the number labels and margins carefully rather than assuming it will stay sharp on a large canvas.
