How to change the color of specific row in ALV tree

Question

Hi,
I m using method set_table_for_first_display of a class CL_GUI_ALV_TREE.
The req is to change the color of specific row. Now can anybody tell me how to change the color of ALV tree. As in ALV tree and in this method 'set_table_for_first_display', there is no parameter IS_Layout.
Pls suggest...

There are a number of ways to create a fieldcat.
For the purpose of this example i will build the fieldcatalog manualy
by populating the internal table fields individually and then
appending the rows. This method can be the most time consuming but can
also allow you more control of the final product.
Beware though, you need to ensure that all fields required are
populated. When using some of functionality available via ALV, such as
total. You may need to provide more information than if you were
simply displaying the result
I.e. Field type may be required in-order for
the 'TOTAL' function to work.
