Use Group by node with aggregation options concatenate.

Could you share how to Configure? thanks!

It depend on how you load your data. If you load data as a string with coma when first use Cell Splitter. Then in Group by in groups tab add Color to Group Column(s) and in Manual Aggregation tab add Material# then in Aggregation (click to change) drop down column chose - Concatenate.
