The three colours are the Primary Colours.\nRED\n(Magenta) \nBLUE\n(Cyan) \nYELLOW\n\nBy mixing these colours, either two or all three produces every other colour there is.\n\nSecondary colours\nA colour created by mixing two primary colours is called a secondary colour. Green is an example of a secondary colour, which is made by mixing yellow and blue. \n\nTertiary Colours\nMixing all three primary colours creates a tertiary colour, which tend to be earthy tones. Brown's and khaki's are examples of tertiary colours mixed with different proportions of primary colours. Black can also be made by mixing equal amounts of red, yellow and blue.\n\nPrimary colours of light\nMixing coloured light is quite different to paint. Your television will make up all the colours you see on the screen by mixing red, blue and green light.\n\nTen digits are the fingers on your hands with which you can perform every task known to man.\n\nThe seven notes are musical ones,  A, B, C, D, E, F and G with which you can make millions of tunes.\n\nSo it's obvious that by using these things with intelligence you can create almost anything from artistic works to practical artefacts.

Well since you did ask this in the science forum I might as well try answering this in such a manner as akin to scientific method.\n\nStep 1:\nWrite down the 3 Primary colours (Red, Blue and Yellow)\nStep 2:\nWrite down the 3 secondary colours (Green, Purple and Orange) \nStep 3:\nNow write down 2 additional tertiary colours (Brown and Black) \nStep 4: \nPlay the survivor game and eliminate a colour each round.\nStep 5:\nNow that you only have one colour left go to a paint shop and get those strips which show the different hues of the said colour.\nStep 6:\nPlay the survivor game again and eliminate each strip until you are left with only one.\nStep 7:\nFind name of colour which corresponds to the colour strip.

No... you cant make another colour because every colour you could ever try making will be a shade of a colour that already exists. and there is already enough numbers to go on forever, so no.

well let's see IF you MUST have a misc decor and you MUST have a ribbon then:\n\nchoose base 1, type of flower 1, ribbon color 1, misc dec 1\nchoose base 1, type of flower 1, ribbon color 1, misc dec 2\nchoose base 1, type of flower 1, ribbon color 1, misc dec 3\nchoose base 1, type of flower 1, ribbon color 1, misc dec 4\nchoose base 1, type of flower 1, ribbon color 1, misc dec 5\nchoose base 1, type of flower 1, ribbon color 1, misc dec 6\nchoose base 1, type of flower 1, ribbon color 1, misc dec 7\nchoose base 1, type of flower 1, ribbon color 1, misc dec 8\nchoose base 1, type of flower 1, ribbon color 1, misc dec 9\nchoose base 1, type of flower 1, ribbon color 1, misc dec 10\n\n10 combinations there, for each ribbon color = 50 combinations\n\nfor each type of flower = 150 combinations\n\nbut really you can combine types of flowers (1, 2, 3, 1+2, 1+3, 2+3) so for each type of flower is really 250 combinations.\n\nThen you have 2 bases so 500 combinations.
