Save Color value into database (type of integer)

I have a textbox on the form. The users are able to set the textbox backcolor and save it into the database. I was given a field name "textboxbackcolor" in database and the "textboxbackcolor" field is type of integer. So how am i going to update the color type to the database which is an "integer" type ? So that i can load the textbox backcolor next time to the color store in database each time i load the form? For example let's say i set the textbox backcolor to black. And then i click the "Save" button. What value should i fill in the "textboxbackcolor" field ??? Hope someone can help. Thanks in advance.
