The coloring within the vestibule is in shades of blue, and the massive
pillars supporting the three arches are toned in rich terra cotta.



Machinery Hall
One of the Minor Entrances

Flanked by Corinthian columns which reflect, in smaller size, the great
pillars of the main entrance, four minor doorways break the long western
wall of the Palace of Machinery on either side of the central entrance,
the architectural and sculptural design in them being similar to that of
the main portal. The frieze in low relief, encircling the bases of the
columns and representing the genii of mechanics, is repeated from the
larger entrance, as are also the figures in the spandrels, typifying the
application of power to machinery.

The color treatment of these doorways is especially brilliant. The
Corinthian columns simulate Sienna marble. The background in the
spandrels is stained a rich orange. The shell canopy, as in other panels
where it is used throughout the Exposition, is in cerulean blue, the
wall space beneath it is a deep pink, while the door is the customary
green.

The landscape planting along the entire wall is superb. Against the
ivory-tinted background, various species of evergreens are grouped with
consummate skill.
