@studio.purracchio - with all our chatting back and forth, we haven’t found a solution for you. What we should have done was do a forum search … according to Emmanuel in this post it’s not possible Can I change the color of an input's Placeholder text? at least on standard bubble that is. But in another thread, he went on to say those plugin providers could do it safely so I searched the plugins and @lottemint has provided us with a free plugin to do exactly that https://bubble.io/plugin/input-placeholder-color-1532013071429x291243122669649900
Caveat … I have not tried it … yet.
