Hoe kan je je huisdier een verschillende kleuren bij de naam krijgen?

Are you asking about changing the font color or changing your pet’s name? Or asking about changing your pet to another pet?

For the first question, you cannot change the font color of your pet’s name unfortunately :(

For the second question, if you go into your game menu, press/click “Family”, then press/click again on your pet, you can change its name there

For the third question, see answer two but go to the icon that looks like a masquerade mask

Hope I could help!
