The option to change the chart colours is a user specific setting so there is no way to change it for all users at the same time. Each user has to change the colours under their own ID.
To change the martial colours, please follow the below steps:
1. From a patients charting screen, click Tools
2. Select options
3. select the tab "colours"
4. Select the colour next to each material, a colour wheel will appear.
5. select your prefered colour, click ok.
It is not currently possible to change the colour of the text inside the R4 Practice management system
If you think this would be a good idea for the development team to add in the future, please make a post on the ideas page: https://community.carestreamdental.com/t5/PRODUCT-IDEAS/idb-p/practicemanagementideas
