如何使用plotly为子图场景中的每个图指定颜色

import plotly.graph_objects as go
from plotly.subplots import make_subplots

fig = make_subplots(rows=1, cols=2)

trace1 = go.Scatter(x=[1, 2, 3], y=[4, 5, 6], name='Trace 1', line=dict(color='red'))
trace2 = go.Scatter(x=[1, 2, 3], y=[7, 8, 9], name='Trace 2', line=dict(color='blue'))

fig.add_trace(trace1, row=1, col=1)
fig.add_trace(trace2, row=1, col=2)

fig.update_layout(title='Subplots with Custom Colors', showlegend=False)
fig.update_xaxes(title_text='X-axis', row=1, col=1)
fig.update_yaxes(title_text='Y-axis', row=1, col=1)
fig.update_xaxes(title_text='X-axis', row=1, col=2)
fig.update_yaxes(title_text='Y-axis', row=1, col=2)

fig.show()
