-# RWTH Colors
+# Colors

 When using `rwth_nb.plots.colors`, the RWTH [Corporate Design](http://www.rwth-aachen.de/cms/root/Die-RWTH/Einrichtungen/Verwaltung/Stabsstellen/Marketing/~eqbm/Corporate-Design/) color scheme is stored in a dictionary called `rwth_colors`. When loading `rwth_nb.plots.mpl_decorations`, the RWTH colors are propagated to Matplotlib as well. The following colors may be used:

 ``` python
 import matplotlib.pyplot as plt
 from rwth_nb.plots import colors

 # adapted from https://matplotlib.org/2.0.0/examples/color/named_colors.html
 colors = colors.rwth_colors;
 fontsize = 12
 ncols = 5; nrows = len(colors.keys()) // ncols + 1;

 fig, ax = plt.subplots(figsize=(12, 6))
 X, Y = fig.get_dpi() * fig.get_size_inches() # Get height and width
 w = X / ncols; h = Y / nrows

 for i, name in enumerate(colors.keys()):
    col = i % ncols
    row = i // ncols
    y = Y - (row * h) - h

    xi_line = w * (col + 0.05); xf_line = w * (col + 0.25); xi_text = w * (col + 0.3)
    ax.text(xi_text, y, name, fontsize=fontsize, horizontalalignment='left', verticalalignment='center')
    ax.hlines(y + h * 0.1, xi_line, xf_line, color=colors[name], linewidth=(h * 0.6))

 ax.set_xlim(0, X); ax.set_ylim(0, Y); ax.set_axis_off();
 fig.subplots_adjust(left=0, right=1, top=1, bottom=0, hspace=0, wspace=0)
 ```

 When plotting, colors are cycled through for each graph by following order:
 > *blue, orange, green, red, purple, bordeaux, violet, black-50, maigrun, turquoise*

 %% Cell type:code id: tags:

 ``` python
 import numpy as np
 import rwth_nb.plots.mpl_decorations as rwth_plt

 x = np.linspace(-2, 2, 501)

 fig, ax = plt.subplots()
 ax.set_ylim(-2, 2)
 rwth_plt.axis(ax); rwth_plt.grid(ax)

 for n in range(10):
    ax.plot(x, x**n, label=r'$x^{}$'.format(n))

 ax.legend();
 ```

 For custom coloring, use as below.

 %% Cell type:code id: tags:

 ``` python
 import numpy as np
 import rwth_nb.plots.mpl_decorations as rwth_plt

 x = np.linspace(-4,4);

 fig,ax = plt.subplots();
 ax.plot(x, x**2, 'rwth:blue');
 ax.plot(x, x**2 + np.random.randn(len(x)), '.', color='rwth:green');
 ```
