Modifier couleur de fond d'un champ de texte

Hi Gladys

We are sorry for the trouble. As described you want to chnage the color of the text field

We need some more information for a better understanding:

• Is this a comment text field or a PDF form text box?
• What is the application and the version you are using? To check the version Go to Help > About Adobe Acrobat /Reader DC
  Make sure you have the latest version 20.006.20042 installed. Go to Help > Check for Updates.
• You may also try to repair the installation (For Windows Only) Go to Help > Repair Installation and see if that works for you.

You may refer to a similar discussion (https://community.adobe.com/t5/acrobat/how-can-i-use-fill-color-on-acrobat-pro-dc/td-p/8950531?page=1) to change the clor of the comment text box.

If you are referring to the PDF form text box, please refer to the similar discussion (https://answers.acrobatusers.com/Change-Background-color-for-a-text-box-q64968.aspx)
Note: Steps are same for Adobe Acrobat DC

Let us know how it goes.

Regards

Amal
