I found this image by doing a google search for "fire fighter Donald Duck coloring image" you can find so many different images that you can print on X-Press Blending Card then color. Too Fun and endless images!
This image actually has several different techniques in it....
Donald's Feathers: coloring white! I used W1, W3, & W5 to create the gray/white.
Red Jacket & Hat: R20, R22, R24, R29 & R59. I even added a bit of C7 for the real dark shadows.
Yellow/orange: Y32, Y35, Y38, YR18 Y16
Buckle & number: black spica pen
white highlights: White Gel pen (it kind of blobbed but it's too hard to fix once it is on the image so I left it.)
Sky: B0000
Asphalt ground: dotted with the tip of my sketch markers in order: 0, W1, W3, W5, W1 using less of each color in order. applying wet on wet so that the edges of each dot softens.
Hugs,
