Taurus colors
Taurus uses color codes on many of its widgets. Colors are used to represent two main things:
the state of a taurus device
the quality of (the reading of) an attribute.
Taurus Device state colors
Taurus Device states, as defined in taurus.core.TaurusDevState are
represented by the following colors:
| State | Background | Foreground | Preview |
|---|---|---|---|
| Ready | Green (0,255,0) | Black (0,0,0) | Ready |
| NotReady | Red (255,0,0) | Black (0,0,0) | NotReady |
| Undefined | Gray (128,128,128) | Black (0,0,0) | Undefined |
Taurus Attribute Value Quality colors
The quality of an attribute measures the reliability of the current read value for that attribute. The meanings of the qualities are:
Invalid: there was some problem when trying to read the attribute (the value should not be trusted)
Valid: the attribute was read correctly (no reason to suspect its value validity)
Alarm: the value is valid, but it exceeded its defined alarm limits
Warning: like Alarm but for the warning limits
Changing: the attribute was read correctly but it is being changed at the time of reading (so its value is likely to differ if re-read)
Taurus Attribute value qualities are represented by the following colors:
| Quality | Background | Foreground | Preview |
|---|---|---|---|
| Invalid | Gray (128,128,128) | White (255,255,255) | ----- |
| Valid | Dead Frog Green (0,255,0) | Black (0,0,0) | 10.89 mV |
| Alarm | Orange (255,140,0) | White (255,255,255) | 76.54 mV |
| Warning | Orange (255,140,0) | White (255,255,255) | 64.23 mV |
| Changing | Light Blue (128,160,255) | Black (0,0,0) | 20.45 mV |
