Green screens are used in video production to replace backgrounds and create special effects. The specific type of green used in green screens lacks reds and other colours that are present in human skin tones. When using a green screen, it's important to avoid wearing green, as the chroma key will turn it into the background as well. While you can use a physical green screen, you can also create a green screen background using Microsoft Paint. To do this, open the image you want to edit in MS Paint, select a bright colour not in the image, and trace the outline of the subject. Then, fill in the rest of the background with the selected colour. Save the image and open it in another image editor, such as Photoshop, to replace the green screen with your desired background.

What You'll Learn

Open the image in Paint
To get started on changing your green screen background using Paint, you will first need to open the image in the Paint program. This can be done by clicking on File > Open and choosing the image you'd like to edit.
Once the image is open, you can begin the process of changing the background. The traditional MS Paint program does not allow you to create a transparent image, so you will need to use a solid colour to block out the existing background. You can do this by selecting a bright colour that is not already in the image and tracing the outline of the subject. Then, fill in the rest of the background with this colour.
If you are using Paint 3D, the process is a little different. In this version of the program, you can crop out the section of the image you want to use and then paste it onto a new background. To do this, open Paint 3D and click "Open" in the middle of the window, then browse for your desired file.
After opening your image in Paint or Paint 3D, you will be able to continue with the steps to change your green screen background.

Select the pencil tool
To change a green screen background in Paint, you must first open the image in the Paint application. Then, select the pencil tool for freehand drawing. The pencil tool is usually located in the toolbar on the left side of the application window. Once you have selected the pencil tool, you can adjust the size and style of the pencil stroke. To do this, locate and click on the drop-down menu next to the pencil icon. This will allow you to choose from a variety of pencil sizes and styles to achieve the desired effect.
After selecting the appropriate size and style, double-click the light green box in the upper-right corner of the Paint window. This will set the colour of the pencil tool to light green. Now, carefully draw around the part of the image you want to save. Creating a boundary between the sections of the image will help distinguish the area you want to change and the section you will replace with a green screen. You can zoom in on the image by clicking the '+' icon in the lower-right corner of the window for a more precise selection.
If the left side of your image primarily consists of the background that you want to delete, you can utilise the rectangle drawing icon. Click 'Fill', then 'Solid Colour', and finally, select the light green colour option. Following this, click and drag the light green box across the section you want to remove. This action will block out the unwanted area with a large green box.
Once you have carefully drawn around the desired portion of the image, the surrounding area can be filled with light green. This process involves colouring the space outside the boundary to indicate the section of the photo that will be replaced with a green screen. After completing this step, save the image by clicking 'File' and then 'Save As'. Choose 'JPEG Picture' and enter a filename and save location before finalising by clicking 'Save'.
It is important to note that MS Paint cannot replace the green screen with a different image. To achieve this, you must use a separate photo manipulation program, such as Photoshop, or a video editor. The green screen editing process will isolate your initial subject, allowing you to place it onto another background of your choice.

Outline the area you want to keep
To outline the area you want to keep in MS Paint, you must first open the image in the program. Then, click on the pencil tool, and double-click the light green box in the upper right corner of the Paint window. This will allow you to draw around the area you want to save, creating a boundary between the image and the section to be replaced with a green screen.
You can zoom in by clicking the + icon in the lower-right corner of the window to draw more precisely. If your border is a mix of colours and difficult to select, you can use stencils to mask the area outside of the border and then switch the selection tool to 'Paint Area' mode. This will follow the edge of the stencil in Ruler and Guide mode. Alternatively, you can use the Selection tool (Shift + T) to draw the active selection around your paint, using whichever selection shape works best.
If your image has a background that you want to delete on one side, you can select the rectangle drawing icon, click 'Fill', then 'Solid Colour', and choose the light green colour. You can then click and drag across the section you want to remove, blocking it out with a large green box.

Fill the rest with light green
To change a green-screen background in Paint, you must first open the image in the Paint program. Next, click the pencil or draw tool and double-click the light green box in the upper right corner of the window. This light green colour is important as it is a specific type of green that is easily detectable by the camera and software. It is a flat, non-glossy, fluorescent tint that lacks reds and other colours that are found in human skin tones.
Now, carefully draw around the part of the image you want to save. This will create a boundary between the image and the section of the photo that will be replaced with a green screen. You can zoom in by clicking the + icon in the lower-right corner of the window to draw more precisely.
After drawing the outline, fill in the surrounding area with light green. Depending on your image, you can select the rectangle drawing icon, click 'Fill', then 'Solid colour', and choose the light-green option. Now, click and drag across the section you want to remove to block it out with a large green box.
Once you've added the green screen background, save the image as a new file. You can do this by clicking 'File', selecting 'Save as', choosing 'JPEG picture', entering a file name, and then clicking a save location.
Finally, open the saved image in a different program, such as Photoshop or GIMP, to replace the green screen with your desired background. Unfortunately, MS Paint cannot replace the green screen with another image. However, the green screen background you've created will allow you to easily isolate and remove the background in another photo manipulation software or video editor.

Open in another program to replace the green screen
Once you've added the green screen background to your image in MS Paint, save the image as a new file. To do this, click 'File', then 'Save as', and select 'JPEG picture'. Enter a file name and click a save location, such as your Desktop.
Now, open your image in another image editor to remove the background. You can use any number of non-Paint services, both paid and unpaid, to replace your Paint image's green screen background with a different image of your choosing. Some examples include Photoshop or GIMP.
After opening your image in your chosen image editor, you can begin the process of removing the green screen background. This process will vary depending on the software you are using. However, the general idea is to use the software's selection tools to select the green screen background and then delete or cut it out.
Once the green screen background has been removed, you can replace it with any background of your choice. Simply open the new background image in your image editor and paste your original image on top. Adjust the positioning and sizing of your original image as needed to ensure it fits seamlessly into the new background.

The exact colour doesn't matter as green screen software can isolate anything. However, it's important that the screen doesn't match anything else in the shot. The green used in green screens is a very specific type of green that lacks the reds and other colours that are found in human skin tones.
After the primer dries, apply the green paint with a roller in long, unbroken strokes, making sure the strokes overlap. You don't need to mix or dilute the paint. Wait 60 minutes, then apply a second coat.
