Yes that should be noted.
In the old days it was common for the positive terminal of an electrolytic capacitor to be marked, now it is the norm for the negative terminal to be marked.
If you are not sure and the capacitor is an axial type, (wire each end) then check each end, the end which is solid aluminium is the negative and the end which is insulated from the rest of the can is the positive.

Thanks Herald1360, I have not look at the Plesseys yet and did not know that the Red was the positive end.
Thanks Crackle, I'll pay attention to the construction re - solid end and insulated end.
