The colour is there but the light colours are too light and the dark colours too dark giving high contrast and low colour. I tweaked the histogram by applying "Midtone Compression" which shifts these very light and very dark colours more towards the middle. Because this also causes an overall loss of contrast I then increased contrast again.
Since there is no better way of showing you what I mean than, well... showing you what I mean I have posted the result here assuming you wouldn't mind. If you do it's easily removed.
This is a result of only adjusting relative lightness in the photo. No changes to colour settings like white balance, saturation or hue were made. Just the two I described above. I hope you like it.
When in doubt..... Press the shutter.
