Filter taxonomy term view by referenced taxonomy term Using two taxonomies.

Fruit:

Banana
Orange
Blueberry
Strawberry
Lemon

Fruit taxonomy has a term reference to the color taxonomy

Color:

Red
Orange
Yellow
Blue
Purple
Green

Created a view using the built in taxonomy term view in a content pane::

Fields
Taxonomy term: Fruit Color [this is excluded from display]

Taxonomy term: Name

Filter criteria
Taxonomy vocabulary: Machine name (= Fruit)

Relationships
Taxonomy term: Content using Fruit

[Configure Relationship: Taxonomy term: Content using Fruit
Relate each Content with a Fruit set to the term.
Require this relationship]

View Output::

Red
 Strawberry

Orange
 Orange

Yellow
 Banana
 Lemon

Blue
 Blueberry 

I would like to add a contextual filter to this view that takes the Color taxonomy name from the url and only shows the fruit for that color.

color/red would only show:

Red
 Strawberry

color/yellow would only show:

Yellow
 Banana
 Lemon

I'm stuck on how to add the contextual filter. I've tried taxonomy term name with validation set to change the term name to id. I also tried the fruit_color field with validation set to change the term name to id. 

Should the term name/fruit_color field be configured differently? Do I need to add another relationship?


  Additional info: 
  The view displays taxonomy terms. 
  The result set is empty when I try adding a contextual filter. 
  The relationship field should only show Fruit terms that have been used at least once to tag content.
To answer you question: No, it shouldn't need to be configured differently; it should work the way you describe.
Here is a screenshot of my configuration (following your description) that works as you would expect (you can see the contextual filter in the background set to 'yellow'):



Perhaps you can spot some tiny deviation from your config here.
Good luck in any case!
