As in Photoshop to change the color to transparent?

Hello! I am not familiar with Photoshop, and in the absence of the designer, need your help here in this case:
A picture

Her contrast is dominated by red color. Needed this color to replace transparent. This is necessary in order to be able to beneath the picture of another color or background image, which would be "rayed" through the transparent areas of the original image.

Solution
As an option:
1) Draw circles with the ellipse tool. To merge them into 1 layer (Ctrl+E). Then right-click on the layer and Rasterize layer.
2) to Trace the girl - for example the polygonal lasso tool. Select the layer with the circles - then Select-Modify-Feather (referred to as px to smooth the selection circles of the same shade) and press Delete.
3) Ctrl+click on the layer icon with circles (to highlight), then select the girl and delete.
Save as png.
Thanks for the reply. But the girl's lips (they are also al) also needs to Shine through... if I just make a "hole" then look it will somehow not very. As I understand it - here it is necessary to use layer masks, but I'm not familiar with these Photoshop. - Eusebio62 commented on March 20th 20 at 11:33
And, well, then you can just Select-Color Range, tyk pipette for red and play around with the settings. Then delete the selected area. - yolanda commented on March 20th 20 at 11:36
You can of course create a mask (in the layers panel) at the selected channel, and "unnecessary" places to hold a smooth black brush. Or grey - if you need transparency. Nothing complicated there. - yolanda commented on March 20th 20 at 11:39
Although not the same texture of the lips is lost. Now write another method. - yolanda commented on March 20th 20 at 11:42

Allocated lip - lasso or pendulum.
Save the selection - Select - Save Selection.
Next, Ctrl+J on the layer.
Hide all layers and go to the tab Channels. CTRL+click on the RGB layer. Back in the layers. Then Delete. Clear the selection, and CTRL+Shift+U.
Then again, in the channels tab, and Ctrl-click will load the selection. In the tab layers, delete the layer with the girl the original shape of the lips.
Allocated those 2 layers and merge with Ctrl+E.
p.s. Yes, the layer with the lips can podobrat the opacity to make it brighter.
All, I hope clearly explained)

Get something like this, if a clumsy cut:

@Jayde.Will, as he clearly in the code then the color should be changed, and not in photoshop. - yolanda commented on March 20th 20 at 11:51
@tristin.Bei, right - Eusebio62 commented on March 20th 20 at 11:54
@Jayde.Will, Thanks for the reply, but this is not what is required. Change the color (substrate) will be implemented in software, ie Photoshop out - Eusebio62 commented on March 20th 20 at 11:57
@tristin.Bei, Thanks, this is what you need, the rest I tweak. - Eusebio62 commented on March 20th 20 at 12:00
@Marta.Hagenes, Yes, contact with such things - if I'm not busy, it will help. - yolanda commented on March 20th 20 at 12:03
