One way of coloring a blend feature is via PARTproject -> Show project -> General tab -> Color and texture -> Color. However, this colors the entire part.

Note Area attributes [Face attributes]
As of V11 SP 4, it is also possible to use area attributes (color and material ). However, this function is not downward compatible.
To apply area attributes to blends, you will find the command Feature Attributes.... [Feature attributes...] in the context menu of the blend.
Details on this can be found under Section 5.9.2.8.4, “Detailed example of the Render Material function ”.
Surface selection preferred over edge selection
If edge selection and face selection lead to the same result, in complex cases, basically, use face selection. If only one or two certain edges shall be edited for example, you can decide for the more comfortable and quicker proceeding.
When taking this into account, there will be created less features in CAD systems and there won´t be problems with parametric parts!
Details on face selection can be found under Section 7.6.2.12.5.5, “Face selection”.
For better performance, you can deactivate the preview display [Preview presentation]. Details can be found at Section 7.6.2.12.5.4, “ Preview display and edge visualization for chamfer/rounding ”.
For a STEP export, only STEP should only STEP be used and NOT STEP 3D, as this format does not support the blend feature.
There are a few minor display defects in version 11.00 SP3. They only appear in the PARTsolutions 3D view. When exporting, the part is transferred correctly.
Sometimes the glitch can be avoided by choosing another method for the creation of chamfer or fillet.
If edges do not meet, create the blend as two different blends instead of one “big” blend.
In rare cases, it is possible for a defect to occur in a symmetrical part on a blend in the course of a certain selection sequence of the blends.[80] Changing the order of the selected blends should solve the problem.
In SP3 there is a glitch in the 3D preview when using the Blend feature for a tapered body. The glitch only occurs in the PARTsolutions preview, so that PARTsolutions 2D derivation and exported part will be correctly.[81] There are still some more graphical glitches, but they all should only concern the PARTsolutions 3D view, so that the PARTsolutions 2D derivation and the exported part will be correctly.
