Multi-layer coating film and multi-layer coating film formation method

A multilayer coating film comprising a colored base coating film and an effect base coating film formed on the colored base coating film,

• wherein the hue angle h in the L*C*h color space diagram is within the range of 30° to 70°, and
• when the following formulas hold:
• X=[(C*45)2+(C*75)2]1/2, and
• Y=[(L*15)2+(C*15)2]1/2+[(L*25)2+(C*25)2]1/2,
• Xis 80 or more and Y is 140 or more;
• provided that C*15, C*25, C*45, and C*75 represent the chroma of the multilayer coating film when light is illuminated at an angle of 45 degrees and received at angles of 15 degrees, 25 degrees, 45 degrees, and 75 degrees deviated from the specular reflection light in the incident light direction,
• h represents the hue of the multilayer coating film when light is illuminated at an angle of 45 degrees and received at an angle of 45 degrees deviated from the specular reflection light in the incident light direction, and
• L*15 and L*25 represent the lightness of the multilayer coating film when light is illuminated at an angle of 45 degrees and received at angles of 15 degrees and 25 degrees deviated from the specular reflection light in the incident light direction.
