## Step by step

1. Click ＋ Add input › Generator (bars, solid color…)….
2. Click the generator in the list. Each one shows a thumbnail of the signal.
3. For Solid color, choose the Color.
4. Click Add.


## What is in the list
- Color bars: SMPTE, to line up monitors and test the output.
- Motion test: a moving ball, to check smoothness.
- Bars with tone: Bars + 1 kHz tone, Bars + L/R identification (1 kHz on the left and 400 Hz on the right) and Bars + pink noise.
- Sound only over black: Black + 1 kHz tone and Black + pink noise.
- Picture: Bars 75%, Bars 100%, Gradient, Zone plate, Checkerboard, White and Image noise.
- Solid color: a single-color background (black, chroma, brand color…).
Signals with sound show a ♪ note on the thumbnail.



## Change the color later
In the gear ⚙ on the solid color's thumbnail, choose another Color. It changes right away.
