[Bug]: Changing color using ax.tick_params #24227
Description
Bug summary
When trying to change the color of the x and y axis I am using ax.tick_param.
If I use label color 'r' or labelcolor='#00000077', but if I write label color='grey' or a hex value: #bdbdbd then the background changes too. Is that expected?
This works:
ax.tick_params(labelsize=22, labelcolor='#00000077', top = False, left=False)
This doesnt:
ax.tick_params(labelsize=22, labelcolor='#BDBDBD', top = False, left=False)
Code for reproduction
url='https://raw.githubusercontent.com/Curbal-Data-Labs/Matplotlib-Labs/master/2018w48.csv'
dataset = pd.read_csv(url)
dataset.drop_duplicates(['city','item'], inplace=True)
dataset.pivot_table(index='city', columns='item', values='cost', aggfunc='sum', margins = True).sort_values('All', ascending=True).drop('All', axis=1)
df = dataset.pivot_table(index='city', columns='item', values='cost', aggfunc='sum', margins = True).sort_values('All', ascending=True).drop('All', axis=1).sort_values('All', ascending=False, axis=1).drop('All').reset_index()
# comma replace
for c in df.columns[1:]:
df[c] = df[c].str.replace(',','.').astype(float)
fig, axes = plt.subplots(nrows=1, ncols=5, figsize=(30,10), sharey=True)
colors = ['green','blue','red','black','brown']
col_names = ['Dinner','Drinks at Dinner','2 Longdrinks','Club entry','Cinema entry']
for i, (ax,col,c) in enumerate(zip(axes.ravel(), col_names, colors)):
ax.plot(df.loc[:,col], df['city'], marker='o', markersize=25, lw=0, color=c)
ax.set_title(col)
for i,j in zip(df[col], df['city']):
ax.annotate('$'+str(i), xy=(i, j), xytext=(i-4,j), color="white", fontsize=8)
ax.set_xticks([])
ax.spines[['top', 'right', 'left', 'bottom']].set_visible(False)
ax.grid(True, axis='y', linestyle='solid', linewidth=2)
ax.grid(True, axis='x', linestyle='solid', linewidth=0.2)
ax.xaxis.tick_top()
ax.xaxis.set_label_position('top')
ax.set_xlim(xmin=0, xmax=160)
ax.xaxis.set_major_formatter('${x:1.0f}')
ax.tick_params(labelsize=8, labelcolor = #bdbdbd, top=False, left=False)

This exact code gives me
using 'grey' although I think to recall seeing that once as well within Jupyter Lab ... but I think it was just related to the inline display, not the actual output of .savefig().

I am using Jupyter Lab and I am indeed looking at the inline display. Got it!

I'm sorry, I cannot follow your description.
A wild guess is that you use labelcolor='#77', which is not a valid color name. This is only checked at draw time and can result in drawing some parts of the figure and then raising an exception.
If that's not it, please clean up your original description

Hi @timhoffm ,
It is github that trims the text, it says # 00 00 00 00 77 in reality, same with labelcolor= 'r'.
I think the issue is what @suuuehgi describes, I am using jupiter labs and the issue shows only on the inline display. When I moved the code to power bi it worked.

When writing code in Markdown, you should surround it with backticks. I have inserted some where I think they should go, but I am not 100% certain, so please edit again and correct any that are wrong.
