pycharm报错raise RuntimeError问题

报错内容： raise RuntimeError(_GLYPH_SOURCE_MSG % nice_join(incompatible_literal_spec_values, conjuction="and"))
RuntimeError:

Expected fill_color to reference fields in the supplied data source.

When a 'source' argument is passed to a glyph method, values that are sequences
(like lists or arrays) must come from references to data columns in the source.

For instance, as an example:

source = ColumnDataSource(data=dict(x=a_list, y=an_array))

p.circle(x='x', y='y', source=source, ...) # pass column names and a source

Alternatively, all data sequences may be provided as literals as long as a
source is not provided:

p.circle(x=a_list, y=an_array, ...)  # pass actual sequences and no source

涉及到的代码部分

   #cannot use seaborn palette for bokeh
    palette =['red','green','blue','yellow']
    colors =[]
    for i in range(len(sublist)):
        for j in range(lenlist[i+1]-lenlist[i]):
            colors.append(palette[i])
    #plot with boken
    output_file(filename)
    source = ColumnDataSource(
            data=dict(x=tsne[:,0],y=tsne[:,1],
                cuisine = df_sub['cuisine'],
                recipe = df_sub['recipeName']))

    hover = HoverTool(tooltips=[
                ("cuisine", "@cuisine"),
                ("recipe", "@recipe")])

    p = figure(plot_width=1000, plot_height=1000, tools=[hover],
               title="flavor clustering")

    p.circle('x', 'y', size=10, source=source,fill_color=colors)
    show(p)

请问怎么纠正这个错误啊？
