Mayur,
In the DS planning board profile, you need to use decision table for graphical objects for the resource chart. While defining an "If" condition you can use the table for product and from the field selection use any of the fields for product attributes, for Ex : AT104, a free attribute in location-product master data. Create different graphical objects with the color that you would like to display and assign them if the condition is true.
