Bistre is a brownish color, and wil add that color tinge to the primary olive color. It is extremely difficult (almost impossible) to identify colors that are close in hue on a computer monitor.
In addition, these stamps were in use for a long time, with many printings. The named colours in the catalogue do not represent distinct printings, but rather regions of an entire spectrum of shades.
In your case, the right hand stamp is definitely more olive and the left hand one is less so, but does not have the brownish tinge of "bistre".
It is important for beginners in the field of colour to be reminded that, just because they have two slightly different colours, it does not mean they must necessarily have the two colours listed in a catalogue.

When I questioned the seller of these two stamps as to the colours as what Roy said in his answer this is the answer I received from the seller:
The colours and shades for the Admiral series can be somewhat contentious - the eye of the beholder reigns supreme! Looking at them now in person, side by side they do have distinct bistre and yellow tones to them, while both having an olive base. Keep in mind that the differences in shades can be subjective and very subtle.
I would guess the first one to be Olive Bistre. The second may well be Olive Yellow but seems a little dark.
hi everyone who answered my query I have found a site that would help most but not for me because I am colour blind to some colours and have a hard time with them:
http://dglphilatelics.com/adm_shades.html
could someone looked at this website and now would they be able to tell the difference in the examples I put in my earlier posting as to which colour is which?

From a side by side comparison to the site images it , to my eyes, looks like Yellow Ochre for your first stamp and Olive Bistre for the second.
The first stamp on the left is the yellow ochre dry printing, while the right hand stamp is what Unitrade calls the olive bistre. It is a wet printing. The main problem with Unitrade's colour names is that they do not match any objective standard like the Stanley Gibbons colour Key. I have published a series of posts on the shades of this issue on my blog, where I illustrate the shades and cross reference them to the Gibbons colour key - a tool that can easily be found for $20 or so from any dealer of philatelic supplies.

As others have pointed out, color is very elusive and very subjective. In the Scott Catalogue (referring to stamps described as olive-bistre) Beck found 16 different "versions" of Olive-Bistre being used, clearly different in hue in some cases.
And with olive-yellow there are 7. Etcetera for the other colors in the alphabet of colors.
