A maybe stupid question on color values

Up to now I thought RGBA forms of color would convert like {255,255,255,255} -> {1,1,1,1} - as example
Now I have some (from another app) which are {1, 1.2, 1,1} means some values are above 1.
How to handle?

This all depends on how the application you are scripting handles colors. Can you give us a small snippet of AppleScript that illustrates the problem you are experiencing?

Thanks for responding.
There is no real code yet. It’s just a question which came across while analysing XMLs and thinking about the best way to go from Satimage to “plain” ASobjC
so with the XMLs there are attributes defining the color:
<text-style font="Arial" fontSize="53" fontColor="1 1 1 1" bold="0" italic="0" alignment="center"></text-style>
This is white.
On other places in the XML color is defined as
color="0.9 1.112 0.75 1"
Or values like
<param name="Color" key="9999/24742/24746/5/24748/14/16" value="-0.172828 0.991439 1.00078"/>

Former way was just to multiply by 255 and round (to integer).

Have you read the Color and Color Spaces section of the documents for NSColor?

Some of the documentation about the color creation methods is wrong — several accept values above 1.0, and use extended color spaces in such cases.

Thanks Shane,

I obviously missed that part

Some of its values will be outside of the 0-1.0 range.

That makes me feel like an “idiot” :wink:
But reading it again several times I haven’t found a way to handle:

Sorry for these dumb questions.

Is there a way to list all available colorspaces?

use AppleScript version "2.4" -- Yosemite (10.10) or later
use framework "Foundation"
use framework "AppKit"
use scripting additions

current application's NSColorSpace's availableColorSpacesWithModel:(current application's NSRGBColorSpaceModel)
