Re: [Pharo-users] Problems evaluating message sends in run-time arrays

I would like to create an array with a collection of colour values.
I tried both:
colorList := {Color blue}
and
colourList := {Color named: #blue.}.
In both cases it evaluates to 'Color blue' rather than the Color object.
Why do you rely on text when you can talk to objects?
Open an inspector and get the full power :)
What surprised me was that:
charList := {Character digitValue:35. Character digitValue:33.}.
Does evaluate to an array of two characters. What is going on?
andy inspect the result and you will see that you get an array with two
character.
Color blue
print
Color blue
because Color blue is a color which corresponds exactly to the result of
sending the message blue to Color.
Some meta approach:
Color blue hue
Color blue intensity
if it replies to color message, it is a color.

It is aColor object. It's print string is 'Color blue'. See Color#printOn: for more info. Ah, of course! I completely misunderstood what the inspector was telling me. Thanks very much

I'm away from my Pharo computer to double-check, but is it just that is how
a Color object displays itself ? Maybe have a look at ColorprintOn:
