Here some example of this coloring:
1. Open an image, select the part you want to use (I usually use the rectangular marquee tool holding down the shift key on the keyboard to have a perfect square), copy it (ctrl c), open a new document (ctrl n then click ok), paste it (ctrl v), resize it to 100x100px.
2. Add a New Fill Layer: Layer –> New Fill Layer –> Solid Color… write d9dbf6 in the color palette; set this layer to mode: Soft Light;
3. Add a New Fill Layer: Layer –> New Fill Layer –> Solid Color… write f6f6da in the color palette; set this layer to mode: Overlay, Opacity: 38%;
4. Add a New Adjustement Layer: Layer –> New Adjustement Layer –> Selective Color… with these parameters:
Reds: Cyan: +100, Magenta: -100, Yellow: +100, Black: +100;

5. Copy your base, drag it above all the layers and set this layer to mode: Soft Light;
6. Add a New Adjustement Layer: Layer –> New Adjustement Layer –> Selective Color… with these parameters:
Reds: Cyan: +100, Magenta: -100, Yellow: +100, Black: +100;
