Violet and controlled amounts of white should give you lilac.
You can increase the intensity of the color by adding blue or red.
If you mix really light blue and pastel purple you get lilac.
You can only do this with paint but add white with purple
Lilac color paint is created by mixing purple and white. To achieve the desired shade, you can adjust the ratio of purple to white; adding more white will result in a lighter lilac, while more purple will create a deeper hue.
You can get lilac two ways. One, you can mix red and blue to get violet and then lighten to the shade of lilac with white. You can also eliminate some of the mixing by purchasing a violet or purple paint and then working with it and the white.
Lilac and pink
The colors of a waterlily are pink white or lilac
The result of mixing lilac with grey depends on the respective strengths and quantities of each of the two colors. If the grey is a very light grey, then adding a small amount of pale lilac will produce a grey with a slight lilac tinge. But a dark grey with strong lilac will produce a dull muddy dark color which will be nearer to black than violet! The best way to see the results of mixing grey with lilac is to do some experiments with small quantities of each, noting which strengths and proportions of each produce the color(s) you like. Then you will know how to make that color consistently when mixing greater volumes of paint. However, grey and violet are actually complementary colors, which means they enhance each other when placed side by side. Gorgeous fabrics and wallpapers are often made using simply greys and violets. So these two colors, in different shades/tones of each, and when used beside each other, such as in a pattern, are an ideal basis for a beautiful color scheme.
I think that those two colors would look really pretty together. ~Singer
