The easiest source to use in OBS is the Color Source. The Color Source creates a source made of a single color. While the color source is the least used source when designing a stream, color sources can still be helpful in drafting a stream or creating simple backdrops for other sources. There are only two properties when creating a color source, the width and height, and the color.
Width and Height
Before we talk about all the options of the colors, you need to understand why setting the width and height is important. When you adjust the width and height for color source, you set the width and height in relation to the aspect ratio you need. For example, if you need a color source to be for a 4:3 aspect ratio you should set the width and height you need such as 1024 width and 768 height. If you need specific width and height values for the aspect ratio, there are aspect ratio calculators online that will tell you the width and height you need to set for that color source.
There are exceptions such as if you need to use color source to make a banner then you will want to set the width and height that will meet your requirements.
A best practice when setting the width and height is to know the dimension you are going to be working with. While you can adjust the width and height through the preview panel, you will likely get an inaccurate of width and height trying to adjust the size manually.
Color Source only displays a single color but offers a wide variety of ways for you to select the color you want. The first option that you will notice is the basic color palate. OBS has default colors built in that you can select by simply clicking on the desired basic color and selecting the OK button.
Below the basic colors table is the Pick Screen Color button. If you have on your monitor a color that you would like to use you can select the Pick Screen Color button and click on the color and OBS will change the color to what you clicked on.
Another option is the color window where you can select with your mouse and then on the right side adjust the color value to determine the light or darkness of the color.
Below the color window you can be even more specific by changing the color based on either the Hue, Saturation (Sat), and Value (Val) or by Red, Green, and Blue. The max value for each option is at 255 and you should only work with one of these sets.
Finally, there is the HTML value or Hex code. The hex color is determined by numbers and letters that specify the Red, Green, and Blue values, respectively. For example, to display red the HTML value you will need to input is #ff0000. The highest value in hex code is ff and the lowest is 00.
If there are any colors that you would like to save for future use, you can select the white boxes under custom colors, then select the color you want to save and then click on Add to Custom Colors. You’ll be able to save any colors that you like to use for future use.
Create a Color Source
Since Color Source is going to be our first source to work with, here is what I would like you to do.
1. Click on the + sign under the Sources window and select Color Source.
2. Create a new Color Source by clicking OK in the pop-up window.
3. Click the OK button to close the properties.
Remember to set the width and height based on aspect ratio you need. If you need to change the color, you can select the select color button and set the color you need. Color Sources while rarely used when designing a stream, are still useful to learn as the color properties are used with other sources and effect filters.
