Black will block the light yet can create drama by making other colours appear brighter. Be careful using black with other dark colours, as the result could be simply too murky. Black works well with bright, jewel-toned shades of red, blue, and green. Black and colours such as yellow really sing! Black and grey is a conservative combination, as is medium or light blue and black.

Grey is a neutral, balanced colour. All shades of grey can be excellent background colours. Use lighter greys in place of white and darker grey in place of black. Light greys with pastel shades of pink, blue, lavender, and green have a feminine quality. Darken those colours for a more masculine feel. Grey with hot pink can be a little retro. Cool a warm palette by adding grey to rich reds or golden yellows.
