Hand-drawn sketch

First of all, we need to open the app store on the mobile phone, enter the keyword "painting" in the top search bar and click search. You can see that there are many apps that can be used for painting. We need to find and download painting apps that can insert pictures and add layers, such as Miaobi, medibang, Samsung Sketchpad and so on.

After opening the painting app, we need to click the layer icon in the upper right corner, then click the blank default layer, and select the second or third function, namely "Import Picture" and "Import from Camera". If you have saved photos of hand-drawn line drawings in your album, just click the second function.

Select or photograph the line sketch you want to insert, and then click the tick in the lower right corner. We can see that the line sketch picture has appeared in the blank layer of the painting app, and then we need to click the plus sign above the layer bar to add a new layer on it.

Then, we need to click the brush icon in the sidebar above, select the brush type we like, and adjust the brush thickness and transparency appropriately, and then click the palette icon next to the brush to select the color we like.

After choosing the color, we need to put two fingers on the line drawing on the screen and make an unfolding gesture, so that it is convenient to unfold the line drawing picture before drawing it; If you are coloring a character, it is recommended to paint the hair color and skin color of the character first.

Then, we need to add another blank layer. After selecting this layer, we will paint the costumes of the characters in the line draft with bright red and purple. The main reason for adding layers is to avoid accidentally erasing the painted skin color and hair color when using an eraser to modify the color of clothes.

Finally, we only need to add a third layer, and then choose rose and light pink to color the balloons on the characters' hands and the rabbits around them. After painting, we can also click the icon in the upper left corner to save the work in the mobile phone photo album, so that we are not afraid of losing the finished work.

Besides, I'll tell you a little trick. If you want to modify the color quickly, you can also click the third tool icon in the sidebar, select the color filling function, readjust the color palette to the color you want, and then click the local color block you want to modify to change the color with one click.

Special tips

Note that the color filling function will not completely modify the color. It is suggested that after using the color filling function, it is best to enlarge the line draft again and gradually refine the local color.
