Generally, we recommend that you upload visual elements as vectors where possible. Therefore, if your logo is not a SVG file, we recommend that you use Canva’s vectorize app to do this. You can find this app by going to “Apps” on the left side bar and searching for “Tracer”. This app allows you to upload images and turn them into vectors. From there, upload an image file of your logo, and that should add your logo as a vector to the dieline design file.
To change the color of the vector, go to edit your image and select the color duotone. From there, you can edit the color of your logo.
