Hi tcalv,
Depends a lot of the type of room, lighting, style, etc.
For example, if you have a modern style office, with chromed furniture, then a white trim over white walls will look great. But if the style of the office is clasic, with heavy wood furniture, then a white trim over white walls will look odd.
If you wish to post a picture, I will be glad to provide additional advice
In order to set an image here follow these easy steps-->
1 - upload your picture to a free online photoalbum like
Photobucket or
Flickr , for example
2 - Look for the link of your picture (usually, photoalbums provide a "link for a forum" script) --> copy the full URL to the image, (not the page on which the image is located),
3 - In the DIY Forum--> Reply post or open a new post--> Press the 'Insert Image' icon above and paste the link--> or type [img] before the URL and [/img] after it, ensuring that you do not have any spaces before or after the URL of the image
