The color of your walls, flooring and furniture can change your lighting.  Dark colors on the walls, on the floor or in your furniture actually absorbs light.  Light colored walls can reflect and intensify the light.  If you have changed any of these things and you feel like your lighting is not the same you are correct,  it’s not. 

In any remodeling of space, lighting needs to be considered.  How much lighting do you need?  What is the space being used for?  Do you want the space to be warm and cozy or bright and crisp?  Do you need true color appearance- rendering? 

As you are planning to make changes in your home or office be sure to consider how this will affect your light!
