**Title:** Color Illusions
**Summary:**
* A video showcases various color-based optical illusions, tricking the viewer's brain into perceiving colors differently.
* **Illusions featured:**
1. Penguins' belly colors appear different due to background lighting.
2. A mural with seagulls that appear to change color based on background.
3. Identical maple donuts labeled as different flavors (vanilla, strawberry, chocolate).
4. A stoplight with colors perceived differently due to context.
5. An after-image illusion creating ghostly colors.
6. A monochromatic room where colors are revealed with a specific light wavelength.
7. Staring at colors to create tricks on the eyes (e.g., making text or colors fade).
8. A final, flashy animation illusion (with seizure alert).
**Video format:** Interactive, with instructions for viewers to participate in experiencing the illusions.
Here are the key facts extracted from the text, excluding opinions and keeping each fact as a short sentence with a number:
1. The video features various color illusions and tricks.
2. In one illusion, two penguins appear to have different belly colors, but are actually the same gray color.
3. The brain accounts for the same color under different lighting circumstances.
4. A mural is created using the Pixma printer by Canon, the video's sponsor.
5. Three teammates (including Keyshawn and Nick) help create the mural.
6. In another illusion, three seagulls appear to be different colors (purple, orange, and a hidden third color), but are actually the same color.
7. The third seagull appears to change color due to a gradient effect with its background.
8. Three donuts labeled as different flavors (white vanilla, pink strawberry, and brown chocolate) are actually all maple donuts.
9. Color can alter one's perception of taste.
10. A stoplight illusion demonstrates how color is perceived in context.
11. Overlays on a stoplight image make gray lights appear as yellow, red, or purple due to contextual influence.
12. The brain uses context to fill in expected colors (e.g., seeing blue as yellow due to the color wheel).
13. Staring at an image long enough can create an "afterimage" or "ghostly image" effect.
14. An animation trick creates the illusion of a yellow duck appearing, even though it's not there.
15. In a monochromatic room with only amber light, objects appear desaturated (various grays).
16. Introducing other light sources reveals the true colors of objects in the monochromatic room.
17. Certain paintings can appear different (e.g., dark gray to blue) when light is introduced in the monochromatic room.
18. Some illusions work better on larger screens (e.g., desktop or larger tablet).
19. A seizure alert is provided before a flashing animation illusion.
20. The final illusion involves staring at a flashing "Z logo" animation to create a warping effect.
