Returns the value of the colour given.



Argument Description
col The colour to check

Returns: Real


This function will return the value (luminosity) of the given colour. This is the amount of the "light" that is mixed into the final colour and is part of the hue, saturation and value method for defining a colour. The following image illustrates how this value corresponds to the HSV scale of colour:


col = make_colour_hsv(random(255), 255, colour_get_value(c_teal));

The above code gets the value used to make the colour constant "c_teal" and then uses that value to set a random colour to have the same luminosity, storing the resulting colour in the variable "col".
