Google Chrome extension used to transform colors on websites into color-blind friendly pallets.
💻 Available on the Google Chrome Store as an add-on.

Protanopia Color Profile
This tool operates by applying a feColorMatrix transformation matrix against the color space of a page.
For example, we may transform the color purple to a more distinguishable color for those who experience Protanopia.
Let $x$ be the vector representing the current normalized RGB color code and let $A$ be the transformation matrix to
transform $x$ to a new color friendly space. Use $T(x)=Ax$ to calculate the resulting RGB vector. We calculate the
transformation for the RGB code rgb(159, 43, 104) to be rgb(109, 108, 89).
$$A=\begin{bmatrix}
0.567 & 0.433 & 0 & 0\\\
0.558 & 0.442 & 0 & 0\\\
0 & 0.242 & 0.758 & 0\\\
0 & 0 & 0 & 1
\end{bmatrix}
, x=
\begin{bmatrix}
159\\\
43\\\
104\\\
1
\end{bmatrix}$$
$$\begin{bmatrix}
0.567 & 0.433 & 0 & 0\\\
0.558 & 0.442 & 0 & 0\\\
0 & 0.242 & 0.758 & 0\\\
0 & 0 & 0 & 1
\end{bmatrix}
\begin{bmatrix}
159\\\
43\\\
104\\\
1
\end{bmatrix} =
\begin{bmatrix}
109\\\
108\\\
89\\\
1
\end{bmatrix}$$
