2D Multi-color Optimization:

$$ \begin{aligned} \hat{u_t}, \hat{l}{(p,t)} \leftarrow \argmin{u_t, l_{(p,t)}} \mathcal{L}\left( \sum_{p=1}^3 \sum_{t=1}^3 |l_{(p,t)} e^{i \lambda_p u_t} * h_p |^2 , sI_p \right), \end{aligned} $$

2D Multi-color Optimization:
$$ \begin{aligned} \hat{u_t}, \textcolor{3cff19} {\hat{l}_{(p,t)}} \leftarrow \argmin_{u_t, \textcolor{3cff19} {l_{(p,t)}}} \mathcal{L}\left( \sum_{p=1}^3 \textcolor{fbff00}{\sum_{t=1}^3} |\textcolor{3cff19} {l_{(p,t)}} e^{i \lambda_p u_t} * h_p |^2, sI_p \right), \end{aligned} $$
