Here is a handy little trick open the colour gallery and expand the standard colours folder, these are the colours that appear on your colourline. right click the folder and untick show on colourline. Now double click each one to add it back to your colourline as a named colour! Yes I admit its a bit of work ( not as much though as naming a whole bunch of colours) but once all the colours are added back you could save your document as a template and even set it as your default template so you would always have a full set of named colours on your colourline.
