Color model stays on hex once declared

[ejsandoval]

When removing the color model from hex to default by just erasing the model statement, the UI stays on the hex model and doesn't return to the default model unless it's stated in the input or changed manually in the UI.

To Reproduce Steps to reproduce the behavior:

1. Create a project and set a color input with the hex model.
2. Run the project.
3. Remove the color model definition.
4. See error

Expected behavior Once erased, the color mode input should reset to the default (rgba).
