Those are the only two pullets and cockerel I have that are 12 weeks old. There are 2 more pullets that are 5 weeks but are from the same line so I don't expect much different results. i will try test breeding and see what happens. Since there is only 1 cockerel, I cannot separate him or he will go crazy. I can probably take two 14 week old Brahma pullets and put him with them if he keeps on trying to mate, or take the two Legbar pullets and put them in a separate coop. Lets see!Pullet - Your pullet lacks double cream gene (ig/ig). Whether they are single carriers for cream or lack cream entirely is not really evident unless you breed them to a known carrier of cream and they produce any cream birds. If your male is a carrier for cream either single or double you will produce a small percentage of offspring that carry cream and a smaller percentage of birds that carry double cream if your pullets carry any cream at all. If nothing cream comes of this process and your male appears to carry cream then your pullets probably lack any cream. You can keep the offspring from these mating and breed them back to the father and produce cream birds if any of them carry the cream gene but you may not be able to still tell which pullets are carriers and which are not. It will require test mating or just mating them and keeping only the cream offspring if any are produced.
The gold tone in the hackle is a clear indicator that she is not double cream. If the other pullet is similar in tone then the same applies to her. If darker then it may indicate she carries no cream and this girl carries single but I have found that the only clear way to tell is to breed and hatch and grow out a lot of birds. An easier way would be to simply get cream pullets for your boy.
The cockerel - So far he looks good. There is some color coming out on his saddle but his shoulders and back look good so far so he may not have the melanizer issues of too much chestnut on the shoulders. He may be single if not double cream and workable in a cream program if that is your desire.
I have worked and still teach Graphic Design so I am more familiar with the Pantone colors. A new printed one is great but online it is subject to a vast number of deviations on different devices and subjective issues. Color charts are nice but they need to be replaced every few years as the tones of the colors tend to mellow or darken. I use one for my Marans eggs but I have 2 and notice that one has changed slightly than the other over the years I've had them. I doubt very much there is a chart that can indicate the percentage of gold or cream in a bird. Legbars are either single, double or zero carriers of cream and the color of the bird is determined by the levels of melanin, whether pheomelanin, eumelanin or autosomal and enhancers, diluters and melanizers, etc, and a chart cannot indicate the influence of any of those.

I agree with KPenley - give them sometime to see if they mellow out. I have a bunch of mixed ages and sexes and in my switching and adding I have had a couple of the older boys attempt the mount but then they stopped.... and yes I have the juvie crowing starting... I am not sure how long this will work but if you pull him you may want to do so with at least one more boy to keep him company. I try to keep my boys in groups for as long as possible until I choose my keepers.
