To make colours brighten up a place or artwork, it is arranged in many different ways. One such foolproof way is by using colour schemes. One of the first things taught in design class, it is helpful if you quickly need to decide what colours should and shouldn’t be included in your artwork.
The first colour scheme includes the primary colours: red, yellow and blue. The colours of a secondary colour scheme are got by mixing the primary colours. These are orange (red & yellow), green (blue & yellow) and violet (red & blue). From these, you can pick warm colours like red, yellow and orange to create a warm effect (think of a sunny day which the sun shining brightly) or use blue, green and violet for a more cooler or calm effect (remember that view of the sea where it stretched till it almost looked as though it was touching the sky?)
If you want to use only one colour instead of three you can opt for a monochromatic colour scheme. Simply mix your colour with different amounts of black and white to create a lighter or darker shade.
Need something to stand out? a complementary colour scheme can be used. This scheme uses contrasting colours and can be found on the opposite ends of the colour wheel (Eg. red and green). If you decide to take adjacent colours (Eg. green and blue) from the wheel it becomes an analogous colour scheme. This scheme is lovely if you need to blend colours.
Of course, there are a lot more colour schemes than what I’ve written about, but in the end what matters the most is how you use these colours to colour that beautiful picture.
