This Krtek - Frogs coloring page is a delightfully vibrant scene that could be made even more alive with the right colors. The three green frogs could be shaded with hues of lime, chartreuse, and kelly green. The two brown frogs can take on hues of chestnut, sandy brown, or tan. The lily pads could be painted with soft shades of green, while the log could be burnished with warm shades like russet or auburn. The background could be made more vibrant with a combination of sky blue, fern green, and Indian yellow. The plants could be a combination of moss green, tan, and brown. An added touch of twinkling golden or silver glitter will make these frogs a joy to look at.
