Screen Printing & Textile Design

Generate harmonious color palettes from a base color. Complementary, analogous, triadic, tetradic, monochromatic. CSS variables, Tailwind config, WCAG contrast.

Calculate total ROI and net gain or loss, then use CAGR for endpoint-only investments or money-weighted IRR for explicit year-end contributions.

Professional color picker with HEX, RGB, and HSL conversion, WCAG contrast checking, and palette generation. Pick colors and copy CSS-ready values instantly.

Generate scan-testable URL, email, phone, WiFi, or escaped vCard QR codes with UTF-8 capacity checks, color warnings, raster logos, PNG, and SVG.

Preview sRGB colors with adjustable color-vision models. Compare palettes and text pairs, check original contrast, and copy the simulated colors as CSV.

Reproduce reviewed square-pixel active-image geometry for a documented target canvas using an explicit Fit/Pad or Fill/Crop mode and rounding rule.

Calculate exact lumber board feet, a user-chosen planning allowance, and a price scenario from measured dimensions and whole-piece count.

Reconcile one uniform rectangular lumber group from actual dimensions, an exact piece count, and a documented density interval matched to the recorded material condition.

Estimate and document one signed radial or tangential dimension change for unrestrained solid wood using a USDA FPL table coefficient or a source-owned coefficient.

Reconcile a symmetric through-dovetail tail-board layout with explicit half-pins, slope projection, uncertainty bounds, and baseline-to-end station coordinates.

Compare 12 transparent orthogonal candidates for up to three rectangular groups on one exact usable plywood stock record.
