Put it into practice
- Choose a small approved color set.
- Keep text contrast predictable.
- Compare the campaign images together.
What this looks like
Product tips use cream backgrounds while launch announcements use the brand purple.
A detail to keep clear
Changing colors for every post can weaken consistency even when each image looks attractive alone.
Using MockupX
A social composition is a separate design from the original product screenshot. Use the output frame to establish shape, then test the exported image in the actual destination preview. MockupX does not publish posts or guarantee a platform will display every pixel without cropping.
Check the result
Keep the original screenshot, then review the exported file at the size where people will see it. Check the message, the visible interface and the final crop separately. For a handoff, record the destination and the approved file so another person can distinguish the final version from a draft.
References and further reading
Use the official references for format behavior and current destination requirements. The composition advice above is a practical design approach, not a promise of platform approval.
