hi elynnya
welcome to the forum.
their coat colours take a long while to develop, changing constantly over their first few months of growth. if you look at the colouring along a kitten's spine & around the back of the ears, you can usually get a good indication of how the colour will set when it's older. we call the orange/red colour "rufous".
if you take a look at madeline's kittens in this thread, you can see the colouring along the spines & around the ears is stronger, this should spread to become rufous all over like the mum.
