Make a dark mode tweet video
X ships two dark themes and most tools offer neither accurately. Dim is navy on #15202b; Lights Out is true black on #000000. Both are here with the exact background, text and divider colours, so a rendered card is indistinguishable from a real dark-mode capture.

The card keeps the author's name, handle and timestamp so your export credits them. The post itself still belongs to whoever wrote it, so check you have the right to reuse it before you publish.
True black is the better pick for video specifically: it costs fewer bits to encode than a mid-grey, it looks correct on the OLED screens most people watch vertical video on, and it avoids the compression banding a dark gradient tends to produce.
Questions
- What is the difference between Dim and Lights Out?
- Dim is navy on #15202b with softer contrast. Lights Out is pure black on #000000 with #e7e9ea text, which is what X uses on OLED.
- Why does black encode better than grey?
- Flat black areas cost very few bits and show no banding, so more of the bitrate goes to the text where it matters.
- Can I get a dark card if my own X theme is light?
- Yes. The theme is a render setting here and has nothing to do with how X is configured on your device.
