CHANGELOG.md

@@ -22,6 +22,10 @@ and this project aspires to adhere to [Semantic Versioning](https://semver.org/s
 - Added ability to do tiled rendering, where tiles covering an image are rendered seperately to form the final image. The default is to do tiled rendering with 1024 by 1024 tiles.
 - Added support for 64 bit IDs
 - Added support for RZ meshes
+- Added support for monochrome plotting 
+
+### Changed
+- Redefined the parameter varification and surprise checking behavior for Filters to instead use a conduit based JSON Schema style verification schema. Implimented for all existing filters. 
 
 ### Fixed
 - Fixed issue where the plot did not align with the 3d axes when the camera was panned (`camera/xpan` and `camera/ypan`).

+Monochrome Plotting
+^^^^^^^^^^^^^^^^^^^

+Generally, plotting is done using a range of colors from a color table; however, in some cases
+monochrome coloring is desirable. In these cases, the single color can be passed as a list of
+RGB or RGBA percentages values between 0 and 1 to the ``color`` node.

 Clamping Scalar Values
 ^^^^^^^^^^^^^^^^^^^^^^
 The minimum and maximum values of a scalar field varies with each simulation time
