The .ocio file extension is associated with 1 MIME types:
A MIME type is a string that tells browsers and other tools how to handle a particular kind of file.
About .ocio Files
OCIO files are plain text profiles used in OpenColorIO systems.
They store text-based color transformation settings. The MIME type text/plain indicates that these files are simple to read and edit with any text editor.
They define color management rules for consistent color processing in digital imaging and film production.
- Contain configuration data for color pipelines
- Are used in visual effects, post-production, and digital imaging workflows
- Can be opened in specialized software like DaVinci Resolve, Nuke, and other color grading tools
- May be modified manually to adjust color conversion settings
Relationship between file extension and MIME type
A file extension is a suffix at the end of a filename that indicates what type of file it is. File extensions help both users and operating systems identify what application should be used to open the file.
File extensions are typically separated from the filename by a period (dot) and consist of 2-4 characters, though they can be longer. For example, in the filename "document.pdf", ".pdf" is the file extension.
File extensions are closely related to MIME types, as they both serve to identify the format of a file. However, while MIME types are used primarily by web browsers and servers, file extensions are used by operating systems and applications.

FAQs
What is an OCIO file used for?
An OCIO file is a configuration file for the OpenColorIO color management system used in visual effects and film production. It defines color spaces and transformation rules to ensure colors look consistent across different software applications like Blender, Nuke, and DaVinci Resolve.
How do I open or edit an OCIO file?
Because OCIO files are stored as plain text, you can view and edit them using basic text editors like Notepad on Windows, TextEdit on macOS, or code editors like VS Code. However, for actual color grading, you load the file into the Color Management settings of your creative software rather than opening it directly.
How do I use an OCIO config in Blender?
To use a custom OCIO configuration in Blender, you can set an environment variable named OCIO on your operating system pointing to the specific .ocio file path. Alternatively, within Blender, navigate to the Render Properties tab and adjust the Color Management settings to reference your desired configuration.
What is the correct MIME type for OCIO files?
OCIO files are typically handled as text/plain because they contain human-readable configuration data formatted in YAML syntax. For more details on how text-based types are handled, you can verify configurations at mime-type.com.
Can I convert an OCIO file to a LUT?
You cannot convert an entire .ocio configuration file into a single LUT because it manages a complex pipeline of multiple color spaces. However, you can use OpenColorIO command-line tools to bake a specific transform defined inside the OCIO file into a standard LUT format (like .cube) for use in software that lacks native OCIO support.
Why are my colors incorrect after loading an OCIO file?
Incorrect colors usually occur if the Input Color Space (IDT) of your media does not match what the .ocio configuration expects. Ensure that you manually assign the correct color space (e.g., ACEScg, sRGB, or LogC) to your imported images or video clips within your software's color management panel.
General FAQ
What is a MIME type?
A MIME (Multipurpose Internet Mail Extensions) type is a standard that indicates the nature and format of a document, file, or assortment of bytes. MIME types are defined and standardized in IETF's RFC 6838.
MIME types are important because they help browsers and servers understand how to process a file. When a browser receives a file from a server, it uses the MIME type to determine how to display or handle the content, whether it's an image to display, a PDF to open in a viewer, or a video to play.
MIME types consist of a type and a subtype, separated by a slash (e.g., text/html, image/jpeg, application/pdf). Some MIME types also include optional parameters.
How do I find the MIME type for a file?
You can check the file extension or use a file identification tool such as file --mime-type on the command line. Many programming languages also provide libraries to detect MIME types.
Why can one extension have multiple MIME types?
Different programs and historical usage may assign various MIME identifiers to the same file format. Listing them together helps maintain compatibility across tools.
