White gives you a PHONY shade of pink!
In order to lighten a shade of red, just keep adding water to the paint! The other way, is to use Buff Titanium, which is NOT a white.
“WRONG!Pink is a value of RED, it is NOT a “TINT”, as no such word is used in painting with watercolor or gouache. It is also a stand alone color.”

The hidden secret in paints
The way paint looks when it comes straight out of the tube is usually very different from how it reacts when you start painting. This is especially true with darker colours; the lighter colours such as yellow often behave much as you would expect, hence why a yellow sun always worked at school.
So the primary colours red, blue and yellow alone are not the whole story. Small amounts of other colours are hidden within each pigment – this gives each colour a colour bias.
Colour theory is misleading.
A colour mixing wheel is a great tool; it is handy to have one in your studio for quick reference.
Remembering all the complementary colours when you are starting painting can be tricky.
However, if you take the theory at face value, you are in for hours of frustration when mixing the colour you want.
What is colour bias?
Every single colour has a bias towards another colour.
A blue pigment will have either a red bias or a green bias compared to another blue pigment.
Colour ‘theory’ states that you can mix all 3 secondary colours with the 3 primaries,
However, this will only work if a ‘pure’ primary colour is used.
With paint pigments, you can’t find a ‘pure’ red, for example, that will make both a good orange (when mixed with yellow) and a good purple (when mixed with blue).
This is because the red will have a bias towards either orange or purple due to the chemical impurities foun d within every pigment. (see What are my Acrylic paints made from?)
A red that has an orange bias (Cadmium Red) will mix a bright orange but will not mix a bright purple.

All these sites reference tints with watercolors.
