Customising Yellow logos

Does anybody have trouble with customising downloaded items in yellow?

I can live with my efforts in matching the custard like yellow (with the arrow in IMG 2846) but I struggle to get a match, using the colour triangle (Img 2845) for the brighter Canary Yellow (highlighted by the square.)

The picture of the player has Canary Yellow shirt and Custard Yellow trousers, can you see what I mean with the logos I’ve altered the colour of and overlaid?

I’ve tried countless times and never get anything I am happy with.

It’s just a bit frustrating as I managed to get a match with the Blues, Greens, Maroon, Pink etc.

Yeah it's pretty tough even if you use the customisable colours at the bottom and copy them over to the logo they still won't match probably and you'll see the outline of the shape I've had this issue too.
