How to make something like this ⬇️
1️⃣ Open Photoshop
Turn the image into an illustration and remove the background (make it transparent).
2️⃣ Color the entire character pure black (#000000):
At this stage, the character will completely disappear when the image is tapped — but…
3️⃣ Place a colored background under the part you want to remain visible when tapped:
Use any color other than black
(e.g. for the eye, place a yellow background behind it).
4️⃣ Export the image with a transparent background:
PNG-24 with transparency.
5️⃣ Upload it to X (Twitter) by dragging the PNG file directly into the tweet, not by using “Add image”.
💡 The idea
Any black color (#000000) inside a transparent PNG
will disappear when the image is opened in X’s image viewer.
