Hello just a general observation/suggestion, sometimes a lesson is recommended by the bot but then we can't take the mini quiz because we already took it recently. So probably the bot should have recommended other lessons instead?

I’ve noticed that ‘violet’ changes with gender and number too, despite being named after a real thing, like orange and rose. 

Is this correct?

Q-)   Choisissez la bonne réponse:

"Nous téléphonons à ami de Nathalie." 

              Ou                               

"Nous téléphonons à l'ami de Nathalie."

From the above two sentences, which one is correct...also please provide me with the appropriate reason for the correct answer.

Hi, Ive just done the question 'What does Je lui parle mean? to which I answered I am speaking to him, and I am speaking to her (I ticked both boxes.) My answer was marked  nearly right but my understanding is that lui can refer to both him or her. Can you explain why it was marked this way please.
