This is a free phone coloring page, that is perfect not only for kids and their parents but also for adults and professional painters.
Earlier phones were very different. There were folding, sliding and generally the most unusual designs. But now all the phones are approximately similar to each other (or rather, all are similar to the iPhone).
And in this regard, the difference is mainly in colors (although even the color is most often black). And so here you will need to apply black and gray colors.
Do not forget to leave a little glare on the screen to make the phone look more voluminous. A small layer of shadows will make your phone even more voluminous and realistic.
So, download or print the phone coloring page and using your favorite colors and tools to colorize the phone.
