Custom legend with RGB Triplet bar graph

I tried to customize my bar graph and my legend with RGB Triplet.
AS you can see the legend doesn't match with my color choice. It should be in purple in the legend.
I tried this solution, but it doesn't work
bh(2) = bar(nan,nan,0.4940 0.1840 0.5560);
What should i Do to have a match ?
figure (5)
%modifié
X=categorical({'small','medium','large'});
X=reordercats(X,{'small','medium','large'});
Y=[5 18 56];
TestL={'Mon','Tue','Wed'};
figure()
b=bar(X,Y);
hold on
b.FaceColor = 'flat';
b.CData(1,:)=[1 0 0];
%b.CData(2,:)=[0 1 0];
b.CData(2,:)=[0.4940 0.1840 0.5560];
b.CData(3,:)=[0 0 1];
bh(1) = bar(nan,nan,'r');
bh(2) = bar(nan,nan);%
bh(3) = bar(nan,nan,'b');
bh(2).CData=[0.4940 0.1840 0.5560];
legend(bh, TestL, 'location', 'best') %'northwest'
%legent at the top
xtips1 = b(1).XEndPoints;
ytips1 = b(1).YEndPoints;
labels1 = string(b(1).YData);
text(xtips1,ytips1,labels1,'HorizontalAlignment','center',...
'VerticalAlignment','bottom')
ylabel('Energie [kWh]')

Hi Jonathan,
I understand that you would like to customize the color appearing in the legend. You can try changing the color by changing the "bh(2).FaceColor". You can try the following code:
%modifié
X=categorical({'small','medium','large'});
X=reordercats(X,{'small','medium','large'});
Y=[5 18 56];
TestL={'Mon','Tue','Wed'};
figure()
b=bar(X,Y);
hold on
b.FaceColor = 'flat';
b.CData(1,:)=[1 0 0];
%b.CData(2,:)=[0 1 0];
b.CData(2,:)=[0.4940 0.1840 0.5560];
b.CData(3,:)=[0 0 1];
bh(1) = bar(nan,nan,'r');
bh(2) = bar([nan,nan]);%
bh(3) = bar(nan,nan,'b');
bh(2).FaceColor=[0.4940 0.1840 0.5560];
legend(bh, TestL, 'location', 'best') %'northwest'
%legent at the top
xtips1 = b(1).XEndPoints;
ytips1 = b(1).YEndPoints;
labels1 = string(b(1).YData);
text(xtips1,ytips1,labels1,'HorizontalAlignment','center',...
'VerticalAlignment','bottom')
ylabel('Energie [kWh]')
Hope this resolves your issue!
