Does your work look just like the pictures?
I do my best to make the pictures look as true to life as possible. The greatest factor effecting how the eye perceives color is the local lighting conditions. I photograph my work under 5000K fluorescent or LED bulbs. I also try to include at least one photo using outdoor lighting.
Video of products are available upon request. The second largest factor that effects perceived color is the device being used to view the website, since each device used can have a varying screen settings.
That being said, I can't say that what you see is exactly what it will look like, but it is likely very close.
