How do you work out colours?

How do you work out the combination of colours, blue, red and green?

Is there are simple way to do so to get yellow, lavender and lighter colours or do you just have to experiment?

thanks

Your asking changing an actor's colour using the RGB numbers in that actor?

I usually go into actor. Click on Color. White will be 0,0,0. Then I will click on the colour box (opens up the colour box) and use the colour eye dropper tool (near the bottom of the box) to pick up a colour I want.

Then the RGB numbers for that colour will show up below.

Like yellow is R .992 G .98 Blue .161

You can look up RGB numbers online by googling the color name with "RGB". For example, if you google lavender rgb you get this: http://www.rapidtables.com/web/color/lavender-color.htm

Then divide the integer value by a constant. So your change attribute values would be something like this:

self.Color.Red: 230/255
self.Color.Green: 230/255
self.Color.Blue: 250/255

I usually Group those three behaviors and label it with the name of the color ("Lavender").

I am wanting to change the background colour of a scene for the sky to various colours depending on what is selected. I have clouds moving over it. I have an attribute backgroundcolour. When background colour is 1 for blue:

change attribute red to ?
change attribute green to ?
change attribute blue to?

When background colour is 1 for purple:
change attribute red to ?
change attribute green to ?
change attribute blue to?

and so on...

Thanks for everyone's help. Very much appreciated.

Happy Easter

If you look at @Socks' gif above, you can click on a color in the color wheel or the crayon tab or whatever you prefer. Then, click on the color sliders tab (it's one of the five small buttons above the color wheel) and you will see the RGB values to include in your change attribute expressions.

For example, here's blue:

So you would use 0/255, 0/255, and 255/255 as the values.

Thanks. This method was the easiest. I have attached how to do the code for the background scene actor.
