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.

What surprised me was that:

charList := {Character digitValue:35. Character digitValue:33.}.

Does evaluate to an array of two characters. What is going on?

'Color blue' is the Color object you created and put in your array. It is aColor object. It's print string is 'Color blue'.

Why do you rely on text when you can talk to objects? Open an inspector and get the full power :)

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.
