How is Wodehouse successful in creating colourfulness out of the character descriptions in ''The Custody of the Pumpkin" in Blandings Castle?

One way Wodehouse is successful in creating
colorful characters is that he chooses
colorful situations, imagery and similes to associate them
with when he describes them and what they do. The two principle characters introduced in
such colorful ways in "The Custody of the Pumpkin" are the Hon. Freddie Threepwood
Emsworth and Lord Emsworth, Freddie's father.

To initially
describe Lord Emsworth, Wodehouse has Emsworth--in a
colorful situation--bungle the operation of his
astronomical telescope. Beach, his invaluable manservant and butler, rescues Emsworth by
suggesting that if perhaps he might remove the cap covering the end of the telescope,
Emsworth might see more than a black void. Emsworth agreeably requests that Beach to do
so while requesting that Beach place the hat he has been holding upon his Lordship's
head, an act Beach is kindly disposed to perform. This colorful situation adds a great
deal of color to Emsworth's character.

'Perhaps if I were to remove the cap at the
extremity of the instrument, ,'lord, more satisfactory results might be
obtained.'

Later,
Emsworth is compared in a
simile to an "elderly prowling leopard," a
colorful simile especially if you note that elderly
leopards are probably missing a good number of teeth and are far less robust than
youthful ones.

Freddie is
associated with a good deal of colorful imagery. His
initial introduction is amidst the imagery of a sunny summer garden swimming in "amber"
color from the sun's golden light that falls on "rolling parks" and "gardens." This
heavenly amber light falls also upon Freddie. The imagery gives a good deal of color
(more than just amber) to Freddie's character.

The morning sunshine descended like an amber
shower-bath on Blandings Castle, lighting up with a heartening glow its ivied walls, its
rolling parks, its gardens ... [and] the white flannels of the Hon. Freddie Threepwood,
Lord Emsworth's second son, hurrying across the
water-meadows.

A later image
has Freddie "sunken in a roseate trance" of love, following a "warm embrace," in a sunny
mood in which he "gambolled up," rather like a "beaming sheep," to encounter his father
who is a bit put out by the witnessed "warm embrace."
