How it works

This color by number submarine set opens on a Submarine with a periscope. Then: a research sub, a periscope above the waves, a porthole view, and submarines at the surface, under ice, over a reef and in the deep sea.

Read the full guide

Seven submarines, seven colors

Each submarine is a different color: red with a periscope, a yellow research sub, green under the waves, black at the surface, purple under the ice, orange over the reef and blue in the deep sea. The eighth sheet, View from a porthole, looks out of one.

Periscope up, periscope down

Two sheets are named for the periscope: the red submarine raises one, and on Periscope above the waves it is all that shows of the green submarine. When it is idle, the periscope of a submarine pulls back into the hull.

  • Blue and yellow are in all 8 easy keys.
  • The easy Submarine under the ice takes 3 crayons, the fewest: blue, purple and yellow.

Questions and answers

Which submarine sheet is the quickest to color?

Periscope above the waves: 90 squares on the easy 12 by 12 grid, because the sky stays white. The Submarine under the ice is next at 105. The other six color 141 to 143 squares.

Is the answer key printed with each submarine?

Yes, as the finished picture in color on page 2; the sheet itself fits one Letter or A4 page. Open More options and uncheck Answer key on page 2 to leave it out.

Why do some squares have no number?

They stay white. Bubbles, glints on the windows, the sky over the periscope and the sheet of ice are paper. Check Put 0 in the white squares in More options to print a 0 in each.

Two kinds of submarine 2

  • Research sub with a round window A small yellow research sub in purple deep water: a big round blue window with a white glint, a red hatch on top, a black thruster at the back, two black skids and a black arm at the front. On the detailed grid the window is light blue with a black rim, the thruster and the arm are gray, two orange lights sit at the front and a small orange fish swims below. A small sub like this is called a submersible: a larger ship carries it to the dive and supports it. Easy: 5 colors, 143 squares to color. Detailed: 7 colors, 570 squares to color.
  • Submarine with a periscope A red submarine under blue water, facing right: a black periscope on its tower, three yellow portholes, a yellow propeller at the back and three bubbles left white as paper. Green seaweed grows on the yellow sand below. On the detailed grid the periscope is gray with a black lens, the portholes are light blue with a white glint, a black line runs along the hull and the seaweed is green and light green. A periscope lets a submarine just under the surface see what is on the water above it. Easy: 5 colors, 141 squares to color. Detailed: 8 colors, 566 squares to color.

At the surface 2

  • Periscope above the waves A black periscope stands above blue waves while the green submarine stays hidden under the water. A yellow sun is in the corner and the sky is left white as paper. On the detailed grid the sky is light blue with a white cloud, the periscope is gray with a black lens and the submarine has a light green stripe. Easy: 4 colors, 90 squares to color. Detailed: 7 colors, 556 squares to color.

Some anglerfish have a lure that glows, which draws prey toward them. Easy: 4 colors, 143 squares to color. Detailed: 6 colors, 569 squares to color.
  • Submarine over a coral reef An orange submarine with two white portholes and a red propeller passes over a coral reef: red and purple corals on yellow sand in blue water. On the detailed grid the portholes are light blue, a red branching coral, a purple fan coral with pink dots and a round red coral with pink marks stand on the sand, light green seaweed grows at the right and two yellow fish swim by.

How this list was compiled: Our own pixel pictures, drawn square by square for this site on 12 by 12 and 24 by 24 grids in October 2026. Nothing is traced, scanned or copied from clip art, and no picture shows a brand, a logo or a character from a film, show, book or game. No submarine copies a real vessel or carries a navy's or a maker's markings, and none is armed. The facts in the Submarine with a periscope, Research sub with a round window and Submarine in the deep sea descriptions, and where a periscope goes when it is not in use, were checked against Wikipedia in October 2026. The color and square counts were counted from the finished grids. Licence: own work
