Converting Colour RGB into a string with padding and gaps

Hello, I am accessing the color of lineplots and want to output them to a text area

b=ax.Children;    
n=numel(b);
ReportMessage(app,'******* Graphics Objects [RGB]  (1=newest) *******');
for i=1:n  
    T=b(i).Type;        %Text or line?
    C=b(i).Color        %Get line colour        
    Lg=b(i).DisplayName;
end    

These colours "C" are doubles in the form

C =

         0    0.4470    0.7410

when i want to create a string from them, if I use this in the loop:

ReportMessage(app,[num2str(i,'%02d'),': ',T,',   color: ',num2str(C,'%.2f'),'   Lgd: ',Lg]);

I get:

01: line,   color: 0.000.450.74   Lgd: 30.0 (^{o}C), 20s Delay
02: line,   color: 1.000.540.00   Lgd: 27.5 (^{o}C), 20s Delay
03: line,   color: 0.250.800.54   Lgd: 25.0 (^{o}C), 20s Delay
04: line,   color: 0.830.140.14   Lgd: 22.5 (^{o}C), 20s Delay

where the colour RGB have no spaces between each component.

How can I get Color, so the 1st line would become (Note I need gaps between the components RGB)

01: line,   color:  0.000    0.447    0.741   Lgd: 30.0 (^{o}C), 20s Delay

T

his is my ReportMessage Function

function ReportMessage(app,msg)
currString=get(app.MessagesTextArea,'Value');
%currString=[{char(msg)};currString];  %add to top of message box
currString=[currString; {char(msg)}];  %add to bottom of message box
app.MessagesTextArea.Value=currString;
drawnow;
scroll(app.MessagesTextArea,'bottom');
end

Use sprintf to make up a custom string with the info you want, then use text to place that string somewhere on your GUI.

Thankyou I.A, this worked

formatSpec = 'Color: %.2f  %.2f  %.2f'; A1=C(1), A2=C(2); A3=C(3);
str = sprintf(formatSpec,A1,A2,A3)
