When binding Color and Opacity setting for a text block, linear colors can not be used

If a user binds the color and opacity settings for a UMG text block they cannot use linear colors directly. They must convert them in to slate colors. When changing the pin on the return node to accept linear colors it cause the following error:

Error Binding: property ' ColorAndOpacityDelegate ' on widget ' TextBlock_25 ' bound to function ' GetColorAndOpacity_0 ', but the sigatnures don't match. The function must return the same type as the property and have no parameters.
