Automatic Data Selection?

I'm trying to create a new spreadsheet to keep a record of orders recieved.

the example attached. What I would like to do is:-

Enter data in the Order Sheet (Sheet 1) under Column C, from a drop down menu taken from Data Sheet (Sheet 2) Column B. I then want Excel to filter the items available from Sheet 2 that correspond to the colour chosen, and once that has been done, I want the part number to be automatically entered.

For example, I order a Red pen, I type/select Red in C2 in D2, I then want Excel to only show the items related to the Red pen Fine nib rd123, Medium nib rd234, Thick nib rd345.
