Even then it's going to cause problems. Black should lead as the primary color rather than follow as a secondary one, because the higher saturation and bolder emphasis of black will shift the balance of the design from "Dash" to "Talk". But reversing it breaks the logo design. That's why I went with a blue-only design.
- Use subtle shades of natural colors.
Subtle colors found in nature also make the best choices for most background or minor elements, especially if type appears on the color.
- Avoid bold, highly saturated primary colors except in areas of maximum emphasis, and even then, use caution.
If black is going to be used, I'd recommend using dark gray instead of solid black.
