Thermostat not turning AC on

We recived a thermostat yesterday,went to hook it up last night. Tested heat fine but will not cut on in cool. Our temp outside is 61 degrees. I got impatient last night and went to bed. This morning it is still not turning on. It is set on cool fan on auto and temp set to where we want it. Please help we’re frustrated.

Do you have any before and after pictures of the wiring on both ends?
