Paste HEX ↔ RGB ↔ HSL output from this tool into PO approval notes. Set palette limits in the Generator against the same HEX list — spot color count directly affects print cost.
Separate screen color from print expectation
sRGB screen math is not Pantone® or lab dip. Confirm critical colors with mill standards; lock the Generator palette after approval.
Build seamless art after palette lock-in
Once approved HEX/RGB values are clear, create seamless repeats in AI Pattern Studio with the same palette. Sample approval should precede PO signature.
Paste approved HEX, RGB and HSL lines from this tool into sample approval notes. sRGB screen color is not Pantone/CMYK — wrong palette causes buyer rejection in mockups.
Validate template and fabric tone in Mockup Studio
The same HEX reads differently on dark vs light grounds — evaluate contrast together on scarf, tee and pillow templates. Match scale/rotate steps in the mockup guide to this palette line.
Open the print PO after buyer approval
After mockup visual sign-off, move the color line from this converter into production; audit mockup credits/cost on Account History.
Palette lock-in prep before upscaling to print size
Lock HEX/RGB/HSL lines on the tech pack
Paste approved HEX, RGB and HSL lines from this tool into sample approval notes. The palette must be fixed before upscaling — sRGB screen color is not Pantone/CMYK.
Match contrast to RIP channels after upscaling
16x upscale can shift fine-line weight and spot-color density. After upscaling, validate the same HEX line on dark vs light grounds — read the Upscale quality guide for the SSIM ≥ 0.85 threshold.
Move approved panel art into Upscale Studio
After palette sign-off, run the same patterns through Upscale Studio to 300+ DPI at final print size. Sample approval should precede PO signature — audit upscale credits/cost on Account History.
This is sRGB screen math for digital tech packs — not a Pantone® / physical lab match. For print-critical color, confirm with lab dips and mill standards.

Digital textile patterns often arrive from web and AI tools as HEX or RGB. Approval conversations are easier in HSL (hue / saturation / lightness). This tool keeps the three formats in sync so palette notes and tech-pack references stay aligned.
Professional B2B color sign-off has three layers: (1) screen reference — align HEX/RGB/HSL with this tool, (2) vector/RIP prep — validate files with the Vectorization Guide, DPI Calculator and Print-Ready Guide, (3) physical sample — real color in your sublimation, pigment or reactive profile. sRGB is not CMYK; print assurance comes only from profile + sample.
SapphireSC (sapphiresc.com) is the B2B AI platform from İlçel Sapphire Tekstil (Bursa): seamless pattern generation, upscale, vectorization and mockups. Free utilities support organic discovery; production continues in the AI Pattern Generator and Vectorizer.

Textile palette practices (reference)
HEX / RGB — standard in AI pattern exports, web mockups and CSS references
HSL — colorway variants: hue shifts, lower saturation for pastels
sRGB ≠ CMYK — screen brightness does not map 1:1 to print ink
#RGB kısa form — #F53 expands to #FF5533; prefer full HEX in tech packs
Before print, validate tile alignment with the Seamless Checker and mesh resolution with the DPI Calculator
Quick reference
HEX — #RRGGBB (or short #RGB); common in CSS and design tools
RGB — red / green / blue channels 0–255
HSL — hue 0–360°, saturation and lightness 0–100%
#FF5733 → rgb(255, 87, 51) → hsl(11° 100% 60%)
Frequently asked questions
What are HEX, RGB and HSL used for?
HEX and RGB describe screen (sRGB) channels; HSL expresses the same color via hue, saturation and lightness for easier tuning. Pattern and UI palettes often move between all three.
How do I convert a HEX code like #FF5733 to RGB?
Each pair is a channel: #RRGGBB → R, G, B (0–255). For example #FF5733 → rgb(255, 87, 51). This tool also expands short #RGB shorthand and keeps all formats in sync.
What is the difference between sRGB and CMYK?
sRGB is the standard for screens and web/AI exports; CMYK is an ink-based print profile. The same HEX can look different on screen vs print — validate print colors in your RIP/profile workflow; this tool only converts sRGB.
Does this match Pantone or convert to CMYK?
No. This tool only converts sRGB HEX ↔ RGB ↔ HSL. It is not a commercial color-library matcher and does not perform CMYK profile conversion — validate print colors in your RIP / profile workflow.
Can I use this for digital textile print color approval?
Yes — for screen references and tech-pack notes, aligning HEX/RGB/HSL is helpful. But sublimation, pigment or reactive print still needs physical samples and profile validation; this tool provides math conversion, not a print guarantee.
Why is HSL useful for pattern recoloring?
In HSL you can shift hue for colorway variants, lower saturation for pastels, or adjust lightness for background contrast. Convert HEX codes from AI Pattern Generator exports to HSL to speed palette decisions.
Why convert color formats in textiles?
AI pattern exports, vectors and web mockups usually carry HEX/RGB, while design teams tweak tone in HSL. A shared reference reduces sample and approval mismatches.
Is this color converter free?
Yes. The converter is free and runs entirely in your browser. Sapphire AI tools such as pattern generation, upscale and vectorization require an account and credits.
