Screen renders a colour incorrectly

I have been taking photos of birds. A few of the photos are Red Bishops.These birds  are in breeding plumage and they are predominately red but with a slight orange tint,. When viewed on my screen they are rendered as a bright orange.  This is true both when using Windows Photo Viewer and my Elements 2018.

How do I rectify the image so that it is a true representation of the bird?

I have used Spyder to calibrate my Monitor using a calibrated print.

    It is possible that the white point setting in your camera needs attention.

    1. Make a selection of the plumage with one of the selection tools, e.g. lasso or selection brush
    2. Place the selection on its own layer (CTRL+J)
    3. Open a Hue/saturation adjustment layer above the layer created in step #2, and clip the layers (CTRL+G)
    4. In the H/S dialog that opens, check "Colorize" and work the 3 sliders to best advantage.

    I found this Red Bishop on Google images.

    I selected the orange using the Magic Wand with a Tolerance of 150 and the Contiguous option unchecked. I clicked on the bird's head to get this selection:

    It didn't quite select all the orange so I used the Lasso tool to select the rest:

    Then added a Hue/Saturation adjustment layer and moved the Hue slider to -18.

    Note that you will might have to try different Tolerance values and/or click on different parts of orange to select as much orange as possible, and then use the Lasso or other selection tool to add or subtract from the selection.

    Thanks,

    I will try this evening.

    I have already tried a similar technique  wirhout being able to bring out the red sufficiently.

    But I did not try colorize.

    I am a little wary of it, it has given me peculiar results in the past!
