Color resources allow you to use a single color or a gradient in your composition without having to import an image or a video for it.
Color Resources can be added in the Compositing Tab:
Parameters
After selecting the resource in the Resource Tab, different Parameters can be changed in the Inspector:
Name
The name of the Color Resource. If not changed manually, it will display the name of the preset color selected, or the R/G/B/A Parameters manually entered. Gradients also affect this name. Once the name is manually changed, the Resource will retain that name.
Color
Clicking this color field will allow you to select a color from a list of named options. This will automatically set the R/G/B/A Parameters to what creates the color, as well as change the Name Parameter as mentioned. A Custom Color can also be selected, which allows the use of a Color Picker, too.
R/G/B/A
The Parameters making up the color range from 0 - 1, 0 being empty and 1 being full. Any value between can be set to create specific colors.
Clamp to [0..1]
R/G/B/A are all clamped by default between the values 0 and 1. By unchecking this option, the Parameters can be set above 1 or below 0, helping you see the values being set through API access or Control.
Gradient
Color Resources can be made to generate a Gradient from one color to another if the above settings are made active and set.
- Active: Turns on the Gradient to be used.
- R/G/B/A: Changes the Gradient's color, adding its value to the resource's Name.
- Angle: What angle the line between the two colors is placed at. By default, it is set to 0 for no angle, so straight up and down.
- Position Main %: Until which percentage of the texture the first color will be fully used. This percentage will be shown in the resource's Name.
- Position Second %: From which percentage of the texture the second color will be fully used. This percentage will be used in the resource's Name.
-
Color: This is the color field for the gradient/second color, which works the same as the first Color and affects the resource's Name.
Resolution
The resolution defines the width and height in pixels that this resource should be treated as.
Warning
Color Resources are internally created as GLSL Shaders. This means they have a default dimension of (1, 1). The Resolution Parameter on the Resource then does not change the actual Resource's resolution, as the shader's UV coordinates are in [0; 1] range. Instead, it is used by the GUI to decide how the resource will be mapped based on the Scale Unit Mode of the Layer that the resource is being used on.
This is important because Color Resources cannot be used with Effects that reference the current content's Resolution, as it will use (1, 1) instead of what is set in the Resolution field. This is a current hard limitation due to how Shaders work, so if you want to apply such Effects on a color resource, you will either need to use a Layer Reference Resource or render the resource into a video or image.
Common Uses
Text Resources
You can use Color Resources with Text Resources to quickly create text to be rendered without needing a plain color image/video.
To do so, place the Color Resource on the Layer inside a Clip, and attach the Text Resource to the Layer. Text that has been input should now appear in that color.
More on the text workflow in the article Text Resource.
Lightcards
Color Resources are commonly used as Lightcards for Virtual Production setups. These will highlight certain areas of the stage, such as the actor, with a specific color and at a specific brightness.
