Draw a collapsed paint tube in Aquarell: distinguish neck, flattened body and crimped tail

A used paint tube combines collapsed surfaces with a neck that retains its shape. Wrinkles everywhere confuse the two. Draw an invented collapsible metal tube in Aquarell, cap beside it and no paint flowing from the mouth. Trace neck, shoulder, flattened body and sealed tail continuously. This is not filling, cutting or using old paint, and remaining shape establishes no capacity estimate.

Set the tube axis and collapsed region

Use an approximately1800×1300 px landscape canvas with pale grey-blue background, neck upper left and sealed tail lower right. Block the uncollapsed envelope, then thin the right half while retaining a rounder left shoulder. Separate body, neck, cap, label and shadow; use silver grey and ochre red. Broaden the body and shorten the neck if toothbrush-like. Retain a firm shoulder and mouth if cloth-bag-like. Collapse is an invented pose, not proof of emptiness, remaining paint, physical volume or product model from pixels.

Give neck and opening one short axis

Draw a short cylindrical neck with a compatible elliptical mouth and narrow near wall. Use deep-grey interior without exposing a bottom; it is not a black dot pasted on the shoulder. Sparse short arcs can suggest threads, not loose metal rings. Reduce a flared rim and straighten walls if funnel-like; add firm volume if cut-rope-like. Do not bend the neck with every body crease. Thread marks suggest appearance, not manufacturable profile, pitch or cap specification, and no contents are being squeezed out.

Expand the shoulder from neck to body

Expand the neck root into a short shoulder joining body width, lighter near and darker far, not an abrupt transverse disc. Hide the label and check one neck-shoulder-body axis with modest asymmetry but continuous connection. Lower a bottle-like rigid shoulder and transition into collapsed body; broaden a balloon-knot-like junction. The task distinguishes regions of relative form retention, not an alloy inferred from colour. A deep black root crack cannot substitute for connected volume.

Build two or three broad collapsed turns first

Arrange two or three broad collapsed faces on the right half, lowered surfaces with some edge thickness and lengthwise undulation, not a twisted rope. Establish ridges and valleys, then model them with values and few sharp creases. Restore side enclosure and residual thickness behind the shoulder if flat paper; lower bulges and soften hard facets if stone-like. Folds belong to this pose, not a regularly repeating pattern. Hide small creases and check that outer contours no longer contradict collapse by remaining a full cylinder.

Make the crimped tail a closed flat band

Taper the lower-right body into a flattened closed tail with two or three pale press lines, not a large open hole. Let the band cross body width and turn with the overall tilt, slightly thicker near. Remove a dark open centre and restore closure if cut-open-looking. Reduce separation and connect both body sides if it looks like an independent clip. Depict an existing crimp without instructions to fold or open a real tube. It is not a sliding accessory, and drawn press lines cannot establish actual seal integrity or leaks.

Turn and compress the label with the folds

Add an unbranded ochre-red band across mid-body, turning around rounded and collapsed surfaces, narrower/quieter in valleys and broader on near faces. It must not float as a flat rectangle or retain constant-width lettering across folds. A colour block can omit capacity and paint names rather than guessing contents. Trace the original band and apply fold occlusion if fragmented. Remove spill onto neck or crimp. Keep it separate and redraw edges after changing large folds instead of retaining old letters to assert continuity.

Distinguish neck and body through metal reflection

Keep a more orderly narrow neck reflection, broken face-dependent body lights and a short flat crimp highlight. Not every crease needs maximum light or pure-black valley. Merge fragmented glints and restore lengthwise form if a foil ball. Add limited metallic value range if rubber-pouch-like while retaining broad surfaces. Place the cap separately lower left, opening sideways/upward and visually compatible with the neck without dimensional specification. Ground each object independently; no black line should imply the detached cap is screwed on.

Save the firm-to-collapsed transition and closed tail

Keep native layers and inspect an exported PNG for coaxial mouth/neck, connected shoulder, varying collapsed thickness, closed crimp and detached cap. Restore firm neck and crosswise tail band if wrinkled cloth, rather than outlining the whole tube black. Reshape envelope and broad folds if apparently full instead of adding only fine creases. Check labels across no gaps and exclude guides. A rolled-tail study needs newly traced material, not a rotated crimp. This checks form, not paint composition, age, usability, automatically estimated capacity or real-product testing.
