My take on Bluestar's family tree (direct lineage only—sorry, Snowfur descendants). The outline/silhouette colours represent clan: blue for Riverclan, green for Thunderclan, yellow for Windclan (apparently Thistleclaw has a Windclan grandfather I'd forgotten about!).

I tried to make everyone fairly genetically plausible coat-wise, at least when recessive genes are taken into account. Pardon any errors, I'm interested in the topic, but not an expert! Making the eye colours realistic would require changing most characters, so I left them as is.

Colourations:
Rooktail - black self
Daisytoe - blue silver tabby with high white spotting
Goosefeather - blue tabby 
Moonflower - black silver tabby 
Stormtail - black self with low white spotting
Oakheart - black tabby with high rufousing
Bluestar - blue self
Snowfur - blue tabby with high white spotting (van pattern)
Blackclaw - black smoke
Mistystar - blue self
Stonefur - blue self
Mosskit - blue tabby with high white spotting
Perchkit - black self
Pikepaw - black smoke
Primrosepaw - blue self
Reedwhisker - black self

Biggest change I made was making Primrosepaw a warm-toned blue. She's canonically "pale creamy-brown" but I couldn't think of any real colour that fits the description which wasn't a bit too much of a stretch for my taste. Only other thing with no basis in canon descriptions is the white blaze I put on Stormtail. I wanted to distinguish him from Rooktail and it works well with Snowfur having white spotting.
