Texture paint not showing up

Hey guys, Im pretty new on blender and have come up on a problem. This is the second model I’ve made this way (the first one worked fine) but this second model, when I change from texture paint mode into object mode, the texture paint only coming up as fully pink? Im not sure how to fix this and could really use some help!!


Btw, sorry i can only add one picture but please just image exactly this but with a coloured texture with the only change changing the mode to texture paint mode
